CVE-2026-55391 1 Koxudaxi 1 Datamodel-code-generator 2026-07-29 7.5 High
datamodel-code-generator generates Pydantic v2 models, dataclasses, TypedDict, and msgspec.Struct from OpenAPI, JSON Schema, GraphQL, Avro, Protobuf, and raw JSON, YAML, or CSV. Prior to 0.63.0, datamodel-code-generator validates a URL host once in src/datamodel_code_generator/http.py through get_body, _validate_url_for_fetch, and _get_ips_from_host, but then lets httpx resolve the host again for the connection, allowing DNS rebinding to bypass allow_private_network=False and reach internal services. This issue is fixed in version 0.63.0.
CVE-2026-62428 1 Xen 1 Xen 2026-07-29 7.8 High
When grant-copy operations are processed, the respective grant may or may not already be in use by another operation (a mapping or another copy). For all copy operations the referenced guest frame is looked up. When another operation is already active for the grant (the grant is "pinned"), what is being supplied back to actually carry out permission checks and copy operation may not be consistent: The permission check may be carried out on a page different from the one involved in the copy.
CVE-2026-59676 1 Selinux Project 1 Selinux 2026-07-27 5.3 Medium
A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in seunshare of selinux policycoreutils allows a user calling seunshare that is running in the unconfined SELinux domain to delete arbitrary root-owned files, This issue affects policycoreutils through 3.10.
CVE-2026-55950 1 Erlang 4 Erlang/otp, Erlang\/otp, Erlang\/ssl and 1 more 2026-07-24 5.9 Medium
Time-of-check Time-of-use (TOCTOU) race condition vulnerability in Erlang/OTP ssl (dtls_packet_demux module) allows an unauthenticated remote attacker to crash all active DTLS sessions on a listener. A DTLS server listener uses a single shared dtls_packet_demux gen_server process to route incoming UDP datagrams to the correct connection handler. When a DTLS client reconnects rapidly from the same source address and port (sending multiple ClientHello messages in quick succession), a race condition in the demux's internal gb_trees key-value store causes a {key_exists, {old, Client}} crash, terminating the demux process. Because the demux is shared across all DTLS associations on that listener, its crash immediately kills every active DTLS session, not just the attacker's. The attack is pre-authentication: the attacker only needs to send UDP datagrams containing valid ClientHello messages from the same source IP and port before the intermediate DOWN monitor message is processed by the gen_server. No credentials, no completed handshake, and no special configuration are required, and the crash can be repeated indefinitely to create a persistent denial of service for all clients of that listener. This vulnerability is associated with program file lib/ssl/src/dtls_packet_demux.erl. This issue affects OTP from OTP 25.3 before OTP 29.0.3, OTP 28.5.0.3 and OTP 27.3.4.14, corresponding to ssl from 10.9 before 11.7.3, 11.6.0.3 and 11.2.12.10.
CVE-2026-16082 1 Sipeed 1 Picoclaw 2026-07-22 5.3 Medium
A vulnerability was identified in Sipeed PicoClaw up to 0.2.9. The impacted element is the function ExecTool.executeRun of the file pkg/agent/pipeline_execute.go. The manipulation of the argument cwe leads to time-of-check time-of-use. The attack must be carried out locally. The exploit is publicly available and might be used. The reported GitHub issue was closed automatically with the label "not planned" by a bot.
CVE-2026-65598 1 N8n 1 N8n 2026-07-22 7.5 High
n8n before 1.123.64, 2.29.8, and 2.30.1 contains a TOCTOU race condition in the Git node's clone operation that allows authenticated users to bypass path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. This lets an attacker plant a crafted repository in the community node directory, which n8n loads as a custom node on the next restart, executing arbitrary JavaScript on the server. Both self-hosted and cloud instances are affected.
CVE-2026-54242 1 Statamic 1 Cms 2026-07-20 4.9 Medium
Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.24 and 6.20.1, the Glide image proxy's URL validation in src/Imaging/RemoteUrlValidator.php and src/Imaging/GuzzleAdapter.php could be bypassed using DNS rebinding. The remote hostname was validated as publicly routable, but resolved again when the image was actually fetched, so an attacker controlling the hostname's DNS could rebind it to an internal address after validation and cause the server to make HTTP requests to internal addresses, including loopback, private network, and cloud metadata endpoints. This affects sites that pass user-supplied URLs to Glide. This issue is fixed in versions 5.73.24 and 6.20.1.
CVE-2024-30084 1 Microsoft 23 Windows 10 1507, Windows 10 1607, Windows 10 1809 and 20 more 2026-07-20 7 High
Windows Kernel-Mode Driver Elevation of Privilege Vulnerability
CVE-2026-63793 1 Linux 1 Linux Kernel 2026-07-20 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ntfs: serialize volume label accesses Protect vol->volume_label with a mutex and snaphost the label before copy_to_user. This prevent a use-after-free when FS_IOC_SETFSLABEL replaces the vol->volume_label and FS_IOC_GETTSLABEL reads it concurrently.
CVE-2026-62212 1 Openclaw 1 Openclaw 2026-07-17 7.1 High
OpenClaw before 2026.5.28 contains a race condition in the MS Teams safeFetch DNS rebinding check. When the affected feature is enabled and reachable, a lower-trust caller or configured input path could win a timing window between the DNS validation check and use, allowing actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.
CVE-2026-53518 1 Better-auth 2 Better-auth\/oauth-provider, Better Auth 2026-07-15 8.1 High
Better Auth is an authentication and authorization library for TypeScript. From 1.6.0 until 1.6.11, the @better-auth/oauth-provider POST /oauth2/token endpoint for the authorization_code grant redeems a single-use authorization code through a non-atomic find-then-delete sequence, allowing two concurrent requests to pass the read step and mint independent access tokens, refresh tokens, and ID tokens; legacy /oauth2/token and /mcp/token paths in oidc-provider and mcp plugins share the same primitive. This issue is fixed in version 1.6.11.
CVE-2026-53517 1 Better-auth 3 Better-auth\/oauth-provider, Better Auth, Oauth-provider 2026-07-15 8.1 High
Better Auth is an authentication and authorization library for TypeScript. From 1.4.8-beta.7 until 1.6.11, the @better-auth/oauth-provider POST /oauth2/token endpoint on the refresh_token grant performs a non-atomic read, validate, revoke, and mint sequence on the oauthRefreshToken row, allowing concurrent requests with the same parent refresh token to pass the revoked check and create forked refresh-token families; the vulnerable range also includes embedded better-auth plugin versions before 1.6.0. This issue is fixed in version 1.6.11.
CVE-2026-4018 1 Blackberry 3 Qnx Os For Medical, Qnx Os For Safety, Qnx Software Development Platform 2026-07-15 6.4 Medium
TOCTOU Race Condition in specific trace commands of the TraceEvent() system call could allow an attacker with local access and with the PROCMGR_AID_TRACE ability, to cause information disclosure, data tampering or a crash of the QNX Neutrino kernel.
CVE-2026-57973 1 Microsoft 1 Windows Subsystem For Linux 2026-07-15 6.3 Medium
Time-of-check time-of-use (toctou) race condition in Windows Subsystem for Linux allows an authorized attacker to perform tampering locally.
CVE-2026-50658 1 Microsoft 1 Defender For Endpoint 2026-07-15 7 High
Time-of-check time-of-use (toctou) race condition in Microsoft Defender allows an authorized attacker to elevate privileges locally.
CVE-2026-54370 1 Acl Project 1 Acl 2026-07-14 6.3 Medium
acl before version 2.4.0 contains a time-of-check to time-of-use (TOCTOU) race condition vulnerability that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link between an lstat() check and subsequent symlink-following operations such as stat(), chown(), chmod(), acl_get_file(), and acl_set_file(). Attackers who control a pathname component can redirect file access control list operations to arbitrary files when getfacl, setfacl, or chacl is invoked by a privileged process over an attacker-controlled path, resulting in local privilege escalation.
CVE-2026-49958 2 Get-hermes, Nesquena 2 Hermes Web Ui, Hermes-webui 2026-07-14 5 Medium
Hermes WebUI before version 0.51.303 contains a time-of-check time-of-use (TOCTOU) race condition vulnerability in the git_discard function within api/workspace_git.py that allows attackers to delete files outside the configured workspace boundary by replacing a validated path component with a symlink after validation but before deletion. Attackers can substitute a workspace-controlled path component with a symlink pointing to an external directory between the safe_resolve_ws() validation step and the subsequent Path.unlink() or shutil.rmtree() deletion call, causing the delete operation to follow the symlink and remove arbitrary files outside the workspace.
CVE-2026-62189 1 Openclaw 1 Openclaw 2026-07-14 7.1 High
OpenClaw versions before 2026.6.9 contain a symlink following vulnerability in the mirror sync feature that allows lower-trust callers to perform actions requiring stronger authorization. Attackers can exploit remote symlink parents to bypass policy checks and authorization boundaries when the feature is enabled and reachable.
CVE-2026-56676 1 Decolua 1 9router 2026-07-13 7.4 High
9Router is an AI router & token saver. Prior to 0.5.2, 9router validates image URLs by resolving the host before fetching, but open-sse/translator/concerns/image.js performs the later server-side image fetch with a separate DNS resolution. An authenticated attacker with access to the LLM proxy can use a vision-capable model and an attacker-controlled DNS name that first resolves to a public IP and then rebinds to an internal address, allowing server-side requests to internal-only HTTP services. This issue is fixed in version 0.5.2.
CVE-2025-58151 1 Xen 1 Varstored 2026-07-10 N/A
varstored is a component of the Xapi toolstack handling UEFI Variables for a VM. It has a communication path with OVMF inside the VM involving mapping a buffer prepared by OVMF. Within varstored, there were insufficient compiler barriers, creating TOCTOU issues with data in the shared buffer. The exact vulnerable behaviour depends on the code generated by the compiler. In a build of varstored using default settings, the attacker can control an index used in a jump table.
