CVSS v3.1 |
| Incorrect Authorization vulnerability in the single-stage query engine of Apache Pinot.
When broker access control is enabled, the single-stage query engine authorizes only the table named in the query's FROM clause. The lookup() transform function identifies its dimension table with a string literal argument rather than through the FROM clause, so that table was never included in the authorization check. An authenticated user who is authorized for at least one table can therefore read columns from any dimension table in the cluster, including tables they have no access to, and can retrieve arbitrary rows of it by supplying primary key values directly. Per-principal row-level security filters configured on the dimension table are likewise not applied.
The multi-stage query engine is not affected.
This issue affects Apache Pinot: through 1.5.1
Users are recommended to upgrade to version 1.6.0, which fixes this issue. |
| This issue affects Apache Fineract versions up to and including 1.15.0. The Center read endpoint (GET /api/v1/centers) and the datatable entry read endpoints (GET /api/v1/datatables/{datatable}/{apptableId} and GET /api/v1/datatables/{datatable}/{apptableId}/{datatableId}) concatenate caller-supplied ordering parameters (orderBy, sortOrder, order) directly into the SQL ORDER BY clause. The existing regex-based input validation can be bypassed, allowing time-based blind SQL injection by any authenticated user with read access to centers or to the targeted datatable.
Users are recommended to upgrade to 1.16.1 which fixes the issue. |
| Improper Neutralization of Special Elements used in an SQL Command ("SQL Injection") vulnerability exists in Apache Fineract (through version 1.15.0). The vulnerability affects the outStandingAmountPercentageCondition parameter of the /fineract-provider/api/v1/search/advance HTTP API endpoint, allowing SQL injection due to insufficient input neutralization. Users are recommended to upgrade to version 1.16.1, which will fix the issue. |
| Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel CoAP component.
This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.2.
When the CoAP consumer could not build its response once the route had completed, CamelCoapResource caught the resulting exception and sent its message back to the CoAP client as the payload of a 5.00 Internal Server Error response. The typical case is a type conversion failure: the consumer converts the final message body to the byte[] payload, and the CamelCoapMaxAge and CamelCoapETag headers to their types, after the route has returned, and therefore outside the route's error handler. On the affected releases the message of such a failure names the class of the value being converted, carries the value's string form, and ends with the class name and message of the underlying cause, so a remote CoAP client could read internal detail about the deployment: class and package names, the string form of the value, such as the path of a file body, and whatever the cause carries, which in practice can include paths, host names and connection detail of a backend. The consumer had no option to suppress this, unlike the HTTP consumers, which offer a muteException option for that purpose. The exception raised by a failing route was not sent: the consumer did not check whether the exchange had failed, and answered a route failure with 2.05 Content and whatever body the message held at that point. Reaching the disclosure therefore requires a route whose completed response a remote client can make unconvertible, which depends on how the route is written.
Users are recommended to upgrade to version 4.23.0, which fixes the issue. If users are on the 4.22.x releases stream, then they are suggested to upgrade to 4.22.2. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.5. The 4.14.x releases stream and earlier, and the 4.15.x to 4.17.x and 4.19.x to 4.21.x release lines, reached end of life before this issue was resolved and will not receive a fix, so deployments on them must move to a supported release. The upgrade is enough on its own: the new muteException consumer option defaults to true on all three fixed release lines, so the error response carries no payload without any configuration change. For deployments that cannot upgrade immediately, make sure the response can always be built once the route has completed: convert the body to byte[] or String as the last step of each route that consumes from a coap endpoint, for example with convertBodyTo, give the CamelCoapMaxAge and CamelCoapETag headers only values of their own types, and add an onException handler that marks the failure as handled and sets the response body explicitly, so that a conversion failure is raised and replaced inside the route rather than in the consumer. |
| Allocation of Resources Without Limits or Throttling in Apache James Mime4J library prior version 0.8.15 allows Denial of Service upon parsing Mime messages.
Users are recommended to upgrade to Apache James server 3.9.1 that relies on fixed MIME4J 0.8.15 which addresses the issue.
See CVE-2026-85108 in Apache James MIME4J library. |
| Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel Docling component.
This issue affects Apache Camel: from 4.15.0 before 4.18.5, from 4.19.0 before 4.22.2.
DoclingProducer builds the command line of the external docling tool and appends to it the custom arguments supplied in the CamelDoclingCustomArguments header, a list of strings whose flags the fix for CVE-2026-40047 restricted to an allowlist. That fix also introduced validatePathSafety to keep path-like argument values inside the intended directory, but the method only looked for relative traversal: it rejected a value containing a traversal sequence such as ../ and a value whose normalized form still held a .. element. It never checked whether a value was an absolute path, and an absolute path without traversal segments contains neither, so it passed unchanged. Every path-like value went through this check, whether it was a separate list element following its flag or was attached to the flag after an equals sign, so an absolute path was accepted in either form, for example as the directory given to the allowlisted --artifacts-path flag, which tells docling where to find its model artifacts. Such a value reached the docling command line as given, so a party able to choose the custom arguments could point the docling process at any directory the Camel process can access, outside the working directory that the check was meant to keep path values in, which is the outcome the CVE-2026-40047 fix set out to prevent. Only the CLI mode, which is the default, passes custom arguments to docling. The header belongs to the Camel header namespace, which consumers applying Camel's default header filtering, such as the JMS and Kafka consumers, remove from incoming messages, so the issue is reached where a route forwards externally influenced values into the header or where a consumer maps incoming headers without that filtering.
Users are recommended to upgrade to version 4.23.0, which fixes the issue. If users are on the 4.22.x releases stream, then they are suggested to upgrade to 4.22.2. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.5. The 4.15.x to 4.17.x and 4.19.x to 4.21.x release lines reached end of life before this issue was resolved and will not receive a fix, so deployments on them must move to a supported release. For deployments that cannot upgrade immediately, do not build the CamelDoclingCustomArguments header from values that originate outside the deployment, remove that header from messages that arrive from outside before they reach a docling endpoint, and make sure that consumers which map incoming message headers drop the Camel header namespace, so that only the route itself chooses the custom arguments. |
| Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel Docling component.
This issue affects Apache Camel: from 4.15.0 before 4.18.5, from 4.19.0 before 4.22.2.
DoclingProducer runs the external docling tool in CLI mode, the default, and tells it where to write the converted document through the --output flag. When the CamelDoclingOutputFilePath header was set, addOutputDirectoryArguments handed its value to that flag verbatim: the value was not normalized, an absolute path or a path containing .. segments was accepted as given, and no endpoint option could confine it to a directory. The custom-argument validation added by the fix for CVE-2026-40047 refuses the --output and -o flags in the CamelDoclingCustomArguments header and tells callers to choose the output directory with this header instead, so the one value that decides where docling writes reached the command line without any of the checks applied to custom arguments. Docling writes the conversion result, as Markdown, HTML, JSON or text, into that directory, naming the file after the input file, and the producer afterwards removes only its own temporary directory, so the file is left in place. A party able to set the header could therefore have conversion output created in any directory the Camel process can write to. The content of such a file is the conversion of the document carried by the message, so it is shaped by whoever supplies that document without being written byte for byte, and when the document content arrives in the message body the producer stores it under a random temporary name, which the output file then carries. The header belongs to the Camel header namespace, which consumers applying Camel's default header filtering, such as the JMS and Kafka consumers, remove from incoming messages, so the issue is reached where a route forwards externally influenced values into the header or where a consumer maps incoming headers without that filtering. The docling-serve mode does not use the header.
Users are recommended to upgrade to version 4.23.0, which fixes the issue. If users are on the 4.22.x releases stream, then they are suggested to upgrade to 4.22.2. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.5. The fix adds an outputBaseDirectory endpoint option that is unset by default, so after upgrading, set it on every docling endpoint whose CamelDoclingOutputFilePath header can carry a value influenced from outside the deployment; without it the header is normalized but can still name any directory. The 4.15.x to 4.17.x and 4.19.x to 4.21.x release lines reached end of life before this issue was resolved and will not receive a fix, so deployments on them must move to a supported release. For deployments that cannot upgrade immediately, do not build the CamelDoclingOutputFilePath header from values that originate outside the deployment, remove that header from messages that arrive from outside before they reach a docling endpoint, and make sure that consumers which map incoming message headers drop the Camel header namespace, so that only the route itself chooses the output directory. |
| Insufficient Session Expiration vulnerability in Apache Camel Keycloak component.
This issue affects Apache Camel: from 4.16.0 before 4.18.5, from 4.19.0 before 4.22.2.
When token introspection is enabled on the camel-keycloak KeycloakSecurityPolicy (useTokenIntrospection=true), the security processor validates the access token of a request by sending it to Keycloak's OAuth 2.0 token introspection endpoint, and accepts the token while the response reports it as active. The introspection endpoint reports a token as inactive once its exp (expiration) time has passed, so on this path the active flag is what enforces token expiry. Introspection results are cached by default (introspectionCacheEnabled=true, introspectionCacheTtl=60 seconds), and both cache implementations shipped with the component, ConcurrentMapTokenCache and CaffeineTokenCache, expired an entry a fixed time after it was inserted, without bounding that lifetime by the exp claim that the cached response already carried. KeycloakSecurityProcessor in turn checked only the active flag of the result, on every path that uses introspection, and never compared exp with the current time. A response cached shortly before the token expired was therefore served to later requests carrying the same token for up to the configured time-to-live after the token's expiry, and those requests were admitted with the roles and permissions the expired token had carried, although RFC 7662, which defines token introspection, states that a response containing exp must not be cached beyond that time. The access token is supplied by the caller with each request, typically as a bearer token in the Authorization header, so a caller holding a token that was valid moments earlier could keep using it after it expired, for as long as the cached entry lived. The window is bounded by introspectionCacheTtl, which is 60 seconds by default and 300 to 600 seconds where the documentation's recommendation for internal services was followed, and it opens only for a token that the same Camel process introspected and cached while the token was still active. The issue grants nothing beyond what the token already carried: it allows no token forgery and no privilege escalation, and token introspection is not enabled by default, which is why the severity is assessed medium. The local JWT verification path, used when introspection is disabled, is not affected by this issue.
Users are recommended to upgrade to version 4.23.0, which fixes the issue. If users are on the 4.22.x releases stream, then they are suggested to upgrade to 4.22.2. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.5. The 4.16.x, 4.17.x and 4.19.x to 4.21.x release lines reached end of life before this issue was resolved and will not receive a fix, so deployments on them must move to a supported release. For deployments that cannot upgrade immediately, set introspectionCacheEnabled=false on the KeycloakSecurityPolicy, so that every request is checked against the introspection endpoint, which reports an expired token as inactive, at the cost of one introspection call per request. Lowering introspectionCacheTtl only narrows the window and does not close it. |
| A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream.
Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1. |
| Improper neutralization of input during web page generation in Apache Wicket.
Apache Wicket generates JavaScript that refers to the elements it renders, and
writes into that JavaScript two values it derives itself: a component's markup
id, and the input name of a form component, which is built from component ids.
Both are placed inside single-quoted JavaScript string literals without being
escaped for that context, so a value containing a single quote or a backslash
ends the literal, and what follows is parsed as script and runs in the
application's origin when the page loads.
A markup id is the value passed to org.apache.wicket.Component#setMarkupId(String),
or the id attribute written in the component's markup, or an id Wicket
generates, in that order. The first two are supplied by the application in an
HTML context, where both characters are legal and where Wicket escapes them
correctly when it writes the same value into the id attribute of the element; a
generated id cannot contain either. An input name is derived from the ids of the
components between the form and the form component, and a component id was
rejected only for ':' and '~'.
In org.apache.wicket:wicket-core on 9.x and 10.x,
org.apache.wicket.markup.head.OnEventHeaderItem#forMarkupId(String, String,
CharSequence) quotes the id it is given into a Wicket.Event.add call, and
components in both wicket-core and wicket-extensions reach it through
#forComponent(Component, String, CharSequence). On every affected version,
org.apache.wicket.markup.html.form.Form writes its markup id and the id of its
hidden-fields container into such literals,
org.apache.wicket.markup.html.form.FormComponentUpdatingBehavior writes an input
name, and org.apache.wicket.markup.html.form.upload.MultiFileUploadField writes
two markup ids and an input name. On 8.x, Form also writes an input name into the
action of a submitting link, and on 8.x and 9.x Form#appendDefaultButtonField
writes an input name into a name attribute with no escaping at all, so a value
containing a double quote escapes the attribute into markup.
org.apache.wicket:wicket-extensions is affected in its own right and not only
through wicket-core: AjaxEditableLabel, AjaxIndicatorAppender,
AjaxDisableComponentListener, UploadProgressBar, KittenCaptchaPanel, Palette,
FilterForm and, on 9.x and 10.x, TrapFocusBehavior and AjaxListPanel each build
their own JavaScript containing a markup id.
An application is affected where a markup id or a component id carries one of
those characters. Wicket does not put one there itself, so the value comes from
the application: an id set on a component, an id attribute in a template, or a
component id derived from data. None of those is a JavaScript context from the
application's point of view.
The Content-Security-Policy that Apache Wicket 9.x and 10.x send by default does
not prevent this. The generated script is written into a script element carrying
the per-response nonce, so the injected code is part of a script the policy
admits.
The fixed versions check an id where it enters instead of escaping each place it
is written. A component id and a markup id may no longer contain a quote, a
backquote, a backslash, braces, angle brackets, a semicolon, an ampersand or a
control character, and a markup id may not contain parentheses or square
brackets either; a component constructed with such an id, or given such a markup
id, fails with an exception.
This issue affects Apache Wicket: from 8.0.0 through 8.19.0, from 9.0.0 through
9.24.0, from 10.0.0 through 10.11.0. Users of Apache Wicket 7.x or older, which
are no longer supported, should upgrade to a supported version. Users are
recommended to upgrade to version 8.20.0, 9.25.0 or 10.12.0, which fix the issue. |
| Apache Wicket 10.10.0, 10.11.0 and 9.24.0 do not set the Content-Security-Policy headers on a page whose render request handler is wrapped in more than one IRequestHandlerDelegate. The framework unwraps only a single delegate level when deciding whether a request renders a page, so with a deeper chain, for example an application-provided delegating request mapper combined with CryptoMapper, the page is served without any CSP header even though CSP is enabled, and no error or warning is raised. The nonce-based protection Wicket applies to inline scripts and styles, together with any other CSP directives configured by the application, is thereby lost for those pages, exposing them to content injection the policy was meant to prevent. Applications on stock Wicket that do not wrap request handlers themselves are not affected. Versions before 10.10.0 and 9.24.0 handled nested delegates correctly. Users are recommended to upgrade to version 10.12.0 or 9.25.0, which fix the issue. |
| Improper neutralization of input during web page generation in Apache Wicket.
org.apache.wicket.markup.html.link.ExternalLink builds a JavaScript click handler and writes it into the tag's onclick attribute whenever the markup tag the component is bound to is not an a, link or area element. The URL held in the component's model is concatenated into a single-quoted JavaScript string literal in that handler without being escaped for that context. The same happens on the neighbouring branch, taken when popup settings are attached, where the value is concatenated into the window.open() call built by org.apache.wicket.markup.html.link.PopupSettings#getPopupJavaScript(). The only escaping applied is the markup escaping that every attribute value receives as the tag is written, which replaces an apostrophe with a character reference. A browser decodes character references in an attribute value before it compiles the event handler, so the apostrophe is restored, closes the string literal, and the rest of the model value is executed as script in the application's origin.
An application is affected where it binds an ExternalLink to a markup tag that is not an anchor, such as a button or a span, and the URL in the model holds data an attacker can influence, which is the ordinary use of the component rather than a misuse of it. Nothing runs until a user activates the element.
This issue affects Apache Wicket: from 8.0.0 through 8.19.0. Users of Apache Wicket 7.x or older, which are no longer supported, should upgrade to a supported version.
Users are recommended to upgrade to version 8.20.0, which fixes the issue. |
| Incorrect behavior order in Apache Wicket: a file path is validated before the framework appends the attributes that complete it.
org.apache.wicket.request.resource.PackageResource asks the configured package resource guard about a path built from the scope class' package and the file name in the request URL, and then hands that same path to the resource stream locator together with a style, a variation and a locale. Those three attributes are decoded from the name of the first query parameter and never appear in the string the guard was given. org.apache.wicket.core.util.resource.locator.ResourceNameIterator appends them to that path, each preceded by an underscore, in the order variation, style, locale, before the file extension, so the file that is opened is not the file the guard approved.
org.apache.wicket.markup.html.PackageResourceGuard decides whether an HTML file is a component's markup template by looking for a class file of the same name beside it, stripping one underscore-delimited suffix at a time as it goes. HTML is on the default allow list, so that check is the only thing separating a static HTML file, which may be served, from a markup template, which may not. Asked about the name of a template, the guard refuses it correctly. Asked about a shorter name for which no class exists, it accepts, and a style supplied in the URL then completes that name into the markup template of a component class, which is written to the response.
An application is affected if the simple name of any of its component classes contains an underscore and no shorter part of that name is itself a class, such as Report_v2 or Wizard_Step1; an application with no such class name is not affected. No unusual deployment, packaging or configuration is required, and running in deployment rather than development mode does not prevent it. Java naming conventions discourage underscores in class names and no module Wicket ships has one, so no framework markup is exposed; what an application exposes this way is its own. A component whose class name has no underscore is not reachable, and neither is its localized or styled markup, because the guard finds the class file under the base name and refuses the request. The attributes cannot change the file extension and cannot leave the component's package, so nothing beyond HTML files in that package is reachable. Access is read-only, and what is disclosed is developer-authored template content: component structure, developer comments, markup that is rendered only under some conditions, inline script, and the endpoints a template names. No user data, credential or session material is reachable this way. An attacker has to name a class in the target package and the component itself, and Wicket writes fully qualified class names into the URL of every package resource it renders.
This issue affects Apache Wicket: from 8.0.0 through 8.19.0, from 9.0.0 through 9.24.0, from 10.0.0 through 10.11.0. Users of Apache Wicket 7.x or older, which are no longer supported, should upgrade to a supported version. Users are recommended to upgrade to version 8.20.0, 9.25.0 or 10.12.0, which fix the issue. |
| Files accessible to external parties in Apache Wicket.
org.apache.wicket.markup.html.PackageResourceGuard decides whether a file on the classpath may be streamed to a client as a package resource. HTML is on the default allow list, so the only thing that separates a static HTML file, which may be served, from a component's markup template, which may not, is a check for a class file of the same name beside it. That check calls getResource() on the class loader that loaded wicket-core. The resource itself is reached through different class loaders: the scope class is resolved through the application's IClassResolver, which uses the thread context class loader, and org.apache.wicket.core.util.resource.ClassPathResourceFinder#find() then tries the scope class' own loader, the context class loader, and the wicket-core loader last.
Where wicket-core is loaded by a class loader that cannot see the application's classes, the check finds no class file, concludes the file is not a component markup template, and serves it. A request for the package resource URL of a component class then returns that component's markup template with status 200. What is disclosed is developer-authored template content: component structure, developer comments, markup that is rendered only under some conditions, inline script, and the endpoints a template names. Access is read-only, and no user data, credential or session material is reachable this way.
Such a deployment is rare. The ordinary packaging, a web archive with wicket-core in WEB-INF/lib, puts the framework and the application in one class loader, so the check finds the class file and the template is refused; those deployments are not affected. The exposure is confined to deployments that give wicket-core a class loader which cannot see the application's component classes: wicket-core placed in a servlet container's shared library directory, in an enterprise archive library directory with the application in the web archive, as an application server global module, or as an OSGi bundle, where wicket-core's bundle cannot resolve a class held by an application bundle. Markup shipped by Wicket's own modules, and by any other code sharing a class loader with wicket-core, remains protected. An attacker has to name a component class, and Wicket writes fully qualified class names into the URL of every package resource it renders.
This issue affects Apache Wicket: from 8.0.0 through 8.19.0, from 9.0.0 through 9.24.0, from 10.0.0 through 10.11.0. Users of Apache Wicket 7.x or older, which are no longer supported, should upgrade to a supported version. Users are recommended to upgrade to version 8.20.0, 9.25.0 or 10.12.0, which fix the issue. |
| Allocation of resources without limits or throttling in Apache Wicket.
org.apache.wicket.markup.html.form.upload.resource.AbstractFileUploadResource is the server side of the form-less upload offered by FileUploadToResourceField, which posts the selected files to a separately mounted resource rather than through a Form. The resource is an application-wide singleton with no component to consult, so newResourceResponse() takes the three limits that bound the upload - the total request size, the maximum size of a single part and the maximum number of parts - from the request parameters maxSize, fileMaxSize and fileCountMax, and hands them to the multipart parser as they arrive. Nothing binds those numbers to the field that is supposed to be uploading. A request naming a very large maxSize is therefore parsed with no effective ceiling on the total size, and omitting fileMaxSize and fileCountMax leaves the per-part and part-count limits unset as well. The values the application configured through FileUploadToResourceField#setMaxSize(), #setFileMaxSize() and #setFileCountMax() are consulted only when the client omits the corresponding parameter, so against a client that supplies one they have no effect at all.
Parts above the parser's in-memory threshold are spooled to the container's temporary directory, and the file parts are then copied into the folder the application's IUploadsFileManager owns, under a sub-folder the request names, where they remain. A part that is not a file is read into the heap in full while the request is parsed. One request, repeatable, can therefore consume as much disk or as much heap as the client chooses to send. The resource carries no authorization annotation and the default authorization strategy permits every resource request, so unless the application authorizes the resource itself the request needs no authentication, no session, no prior page view and no user interaction.
An application is affected where it uses FileUploadToResourceField, or mounts FileUploadResourceReference itself. This is not the ordinary upload path: the resource is a singleton that has to be created and mounted deliberately. An application that configures no upload limit at all loses nothing, because Wicket applies no total-size limit of its own by default; what the defect removes is a limit the application set. Uploads through Form with FileUploadField, and through AjaxFileDropBehavior, are not affected, because both read their limits from the component rather than from the request. The upload resource does not exist in the 8.x line.
This issue affects Apache Wicket: from 9.14.0 through 9.24.0, from 10.0.0 through 10.9.1. Users are recommended to upgrade to version 9.25.0 or 10.12.0, which fix the issue. |
| Memory allocation with an excessive size value in Apache Wicket.
org.apache.wicket.markup.html.form.upload.resource.FileUploadToResourceField uploads files to a separately mounted resource rather than through a form, and is told the outcome afterwards over its own Ajax callback. That callback reads the request parameter filesInfo, a JSON array carrying a client file name, a size and a content type for each file, and turns it into the list of FileUploadToResourceField.UploadInfo that onUploadSuccess() receives. Nothing binds that JSON to an upload the resource performed and nothing re-derives it from the stored files, so the number of entries and every value in them are whatever the request supplied. The callback URL is rendered into the page, no prior upload is required, and both GET and POST reach it, so any client that can load the page can have the component report files that were never uploaded, without authenticating beyond whatever the page itself requires and without any user interaction.
UploadInfo#get(), which the class offers as the way to obtain the bytes of an upload, allocates a byte array from UploadInfo#getSize() before it opens the file. The array is therefore sized by the number the request supplied, and the allocation happens even for a file that was never stored. One small request can cost the server close to two gigabytes of heap, and the request is trivially repeatable, so a few of them exhaust the heap for every request the Java virtual machine is serving. A size that the conversion to int turns negative instead throws NegativeArraySizeException, which the exception handler inside that method does not cover, so it escapes into the application.
An application is affected where it uses FileUploadToResourceField, which is not the ordinary upload path through FileUploadField and Form and has to be extended and mounted deliberately. The allocation additionally requires the application to call UploadInfo#get() rather than reading UploadInfo#getFile() itself. Where the application denies the ENABLE action on the field through its authorization strategy, the callback is refused like any other listener. The 8.x line does not contain this component and is not affected.
This issue affects Apache Wicket: from 9.14.0 through 9.24.0, from 10.0.0 through 10.11.0. Users are recommended to upgrade to version 9.25.0 or 10.12.0, which fix the issue. |
| Improper encoding or escaping of output in Apache Wicket.
org.apache.wicket.core.util.string.JavaScriptUtils#escapeQuotes() replaces each single quote in its input with a backslash and a single quote, and each double quote with a backslash and a double quote, so that the value can be placed inside a JavaScript string literal. It does not escape the backslash, which is the character that has to be escaped, and escaped first, for the rest of that escaping to hold. A value that already holds a backslash immediately before a quote therefore ends up with two backslashes in front of that quote: the first escapes the second, the quote itself is left unescaped, and it closes the literal. Whatever the value carries after that point is no longer text but JavaScript, and it runs in the application's origin and in the session of the user looking at the page. The method is public, is not deprecated, and its documentation states that its result can be part of a JavaScript call such as an alert; the only limitation it notes concerns JSON values, which need different escaping.
An application is affected wherever it calls the method itself and places the result inside a JavaScript string literal, from its own code or from a component of its own or of a third party, and the value it escapes holds data an attacker can influence. There is no further condition, and no component of Wicket has to be involved: the application is using the method for what its documentation offers, and the method does not deliver it.
Two components shipped with Wicket Extensions pass a value through the method. org.apache.wicket.extensions.ajax.markup.html.AjaxEditableLabel writes the editor's first error feedback message into a single-quoted JavaScript string literal in the Ajax response, so an application is affected through that component where the message shown for a failed edit holds data an attacker can influence, whether that is the submitted value itself or another variable the application sets on the validation error. A validation message can carry the submitted value, because input is a message variable that every form component supplies for its own validation errors, and the documentation shows overriding a validator's message to include it; none of the message bundles shipped with Wicket interpolates it, so an application that has not written such a message is not affected through this component. org.apache.wicket.extensions.ajax.markup.html.repeater.AjaxListPanel passes the serialized markup tag of an appended component through the method and is not affected: the tag comes from the panel's own markup file, and a quote in any of its attribute values, the component's markup id included, is written as a character reference by the tag serialization and cannot close the literal.
This issue affects Apache Wicket: from 8.0.0 through 8.19.0, from 9.0.0 through 9.24.0, from 10.0.0 through 10.11.0. Users of Apache Wicket 7.x or older, which are no longer supported, should upgrade to a supported version.
Users are recommended to upgrade to version 8.20.0, 9.25.0 or 10.12.0, which fix the issue. |
| Improper neutralization of input during web page generation in Apache Wicket.
org.apache.wicket.extensions.markup.html.basic.SmartLinkLabel and org.apache.wicket.extensions.markup.html.basic.SmartLinkMultiLineLabel display a text value and turn any URL they find in it into a hyperlink. Both escape the model value and then hand the escaped text to org.apache.wicket.extensions.markup.html.basic.DefaultLinkParser, which searches it for anything of the form scheme://rest and wraps each match in an anchor whose href is the matched text, copied in as it is. The pattern accepts any scheme, and there is no list of permitted schemes anywhere on the path. A text value naming a scheme that executes script therefore becomes an anchor that executes it, in the application's origin and in the reader's own session, when the reader clicks the link. Rendering the page is not enough on its own; the link has to be activated. Escaping does not prevent this and is not the issue: the characters the payload needs are all valid in a URL and are ones that org.apache.wicket.util.string.Strings#escapeMarkup() leaves alone, and the value ends up in a URL rather than in element text, which is a context that escaping model data does not make safe.
An application is affected where it renders text it received through either of these two components. That is what they are for: they exist to linkify email addresses and web URLs found in the data an application is displaying, so untrusted input is the purpose of the feature rather than a misuse of it, and no unusual configuration is involved. No other component uses this parser, and an application that uses neither SmartLinkLabel nor SmartLinkMultiLineLabel is not affected.
On 9.x and 10.x the Content-Security-Policy Wicket sends by default admits script only from a source carrying a per-response nonce, and a URL whose scheme executes script cannot carry one, so that default policy stops the script from running. This is a property of the default policy and not of these components. An application that has weakened or disabled its Content-Security-Policy, for this or for any unrelated reason, is affected in full. Wicket 8.x has no Content-Security-Policy support at all and is affected as it stands.

| Improper neutralization of input during web page generation in Apache Wicket.
org.apache.wicket.ajax.AjaxNewWindowNotifyingBehavior notices that a page instance has been opened in a second browser window or tab. It asks the browser for the value of window.name, which reaches the server as the request parameter windowName, and remembers what the browser reported in a field of the behaviour. That field is part of the page's serialized state, so the remembered value stays in the page store for as long as the page instance does.
On every later render of that page instance the behaviour builds the precondition of its Ajax call by substituting the remembered value into a single-quoted JavaScript string literal, and Wicket writes that precondition into the page as raw JavaScript, because the precondition of an Ajax call listener is script supplied by the caller and is emitted without quoting or escaping. Nothing on that path escapes the value. The window name is client-supplied and Wicket applies no validation to it, so a remembered name containing a single quote ends the literal and the rest of it runs as script in the application's origin, every time that page instance is rendered.
An application is affected only where it has explicitly added AjaxNewWindowNotifyingBehavior to a component. No part of the framework installs the behaviour, so an application that does not use it is not affected. The name the behaviour generates for itself, when the browser reports no name at all, is a random UUID and is not client-supplied.

| Incorrect order of security checks in Apache Wicket.
org.apache.wicket.protocol.http.ResourceIsolationRequestCycleListener obtains the page a request targets before it consults its resource isolation policies, because those policies are passed that page. Obtaining the page instantiates it, and instantiating a page runs the configured org.apache.wicket.authorization.IAuthorizationStrategy. An application that refuses an unauthenticated visitor by throwing org.apache.wicket.RestartResponseAtInterceptPageException therefore throws it from inside the isolation listener, before any policy has run. That exception replaces the request handler, so the policies are never consulted and a request that came from another origin is not refused.
The exception's constructor stores the URL of the request it interrupted, so that Component#continueToOriginalDestination() can resume it once the visitor has signed in. The stored URL is the one the policies would have refused. On sign in Wicket redirects to it, and that redirect is same-origin, so the policies allow it and the listener runs in the newly authenticated session. The whole URL is stored, its query string included, so an ordinary org.apache.wicket.markup.html.form.Form is resumed with the field values the original request carried in its query string and Form#onSubmit() runs with values another origin chose. A form POST is not needed for this; a plain top-level navigation carries them.
An application is affected where it registers ResourceIsolationRequestCycleListener, which is opt-in and is not registered by default, and where it refuses unauthorized access with RestartResponseAtInterceptPageException followed by continueToOriginalDestination(). No application override is involved on that path: IAuthorizationStrategy#isInstantiationAuthorized() documents throwing that exception, org.apache.wicket.authroles.authentication.AuthenticatedWebApplication throws it and org.apache.wicket.authroles.authentication.panel.UsernamePasswordPanel continues to the original destination, and org.apache.wicket.authorization.strategies.page.SimplePageAuthorizationStrategy in wicket-core installs the same pattern. A visitor who is already signed in is not affected, because no interception occurs. Request-body parameters stored alongside the intercepted URL are not applied to the resumed form: the resumption is a redirect, so the resumed request is a GET, and form components read their values from the query string on a GET.
As a workaround, refuse unauthorized access with org.apache.wicket.RestartResponseException instead, which does not store the original destination; visitors are then not returned to the page they asked for after signing in.
This issue affects Apache Wicket: from 9.1.0 through 9.24.0, from 10.0.0 through 10.11.0.
Releases before 9.1.0, which is every 8.x release and 9.0.0, are not affected, because the resource isolation this issue concerns was introduced in 9.1.0. They are not protected either. Their only cross-origin defence is org.apache.wicket.protocol.http.CsrfPreventionRequestCycleListener, which works out where a request came from by reading its Origin header and falling back to its Referer header. Neither header need arrive: a browser does not send Origin on the plain GET a link uses, and the document on the other origin decides through its own referrer policy whether a Referer reaches the application at all. That mechanism therefore never made the guarantee the Fetch Metadata based policy makes, and on those releases a listener invocation from another origin is not reliably refused in the first place. Anyone on a release before 9.1.0 who wants this protection should upgrade to 9.x or 10.x and register ResourceIsolationRequestCycleListener.
Users are recommended to upgrade to version 9.25.0 or 10.12.0, which fix the issue. |
