CVE-2025-66001 1 Suse 1 Neuvector 2026-04-15 8.8 High
NeuVector supports login authentication through OpenID Connect. However, the TLS verification (which verifies the remote server's authenticity and integrity) for OpenID Connect is not enforced by default. As a result this may expose the system to man-in-the-middle (MITM) attacks.
CVE-2025-34066 2026-04-15 N/A
An improper certificate validation vulnerability exists in AVTECH IP cameras, DVRs, and NVRs due to the use of wget with --no-check-certificate in scripts like SyncCloudAccount.sh and SyncPermit.sh. This exposes HTTPS communications to man-in-the-middle (MITM) attacks.
CVE-2025-52919 2026-04-15 4.3 Medium
In Yealink RPS before 2025-05-26, the certificate upload function does not properly validate certificate content, potentially allowing invalid certificates to be uploaded.
CVE-2025-28169 2026-04-15 8.1 High
BYD QIN PLUS DM-i Dilink OS v3.0_13.1.7.2204050.1 to v3.0_13.1.7.2312290.1_0 was discovered to cend broadcasts to the manufacturer's cloud server unencrypted, allowing attackers to execute a man-in-the-middle attack.
CVE-2025-0309 1 Netskope 1 Netskope 2026-04-15 N/A
An insufficient validation on the server connection endpoint in Netskope Client allows local users to elevate privileges on the system. The insufficient validation allows Netskope Client to connect to any other server with Public Signed CA TLS certificates and send specially crafted responses to elevate privileges.
CVE-2025-9708 1 Kubernetes 1 Kubernetes 2026-04-15 6.8 Medium
A vulnerability exists in the Kubernetes C# client where the certificate validation logic accepts properly constructed certificates from any Certificate Authority (CA) without properly verifying the trust chain. This flaw allows a malicious actor to present a forged certificate and potentially intercept or manipulate communication with the Kubernetes API server, leading to possible man-in-the-middle attacks and API impersonation.
CVE-2024-9160 2026-04-15 N/A
In versions of the PEADM Forge Module prior to 3.24.0 a security misconfiguration was discovered.
CVE-2025-11043 1 Br-automation 2 Automation Studio, Studio 2026-04-15 7.4 High
An Improper Certificate Validation vulnerability in the OPC-UA client and ANSL over TLS client used in Automation Studio versions before 6.5 could allow an unauthenticated attacker on the network to position themselves to intercept and interfere with data exchanges.
CVE-2025-9785 2026-04-15 N/A
PaperCut Print Deploy is an optional component that integrates with PaperCut NG/MF which simplifies printer deployment and management. When the component is deployed to an environment, the customer has an option to configure the system to use a self-signed certificate. If the customer does not fully configure the system to leverage the trust database on the clients, it opens up the communication between clients and the server to man-in-the-middle attacks.  It was discovered that certain parts of the documentation related to the configuration of SSL in Print Deploy were lacking, which could potentially contribute to a misconfiguration of the Print Deploy client installation. PaperCut strongly recommends to use valid certificates to secure installations and to follow the updated documentation to ensure the correct SSL configuration. Those who use private CAs and/or self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of their operating system and to the Java key store
CVE-2025-37730 1 Elastic 1 Logstash 2026-04-15 6.5 Medium
Improper certificate validation in Logstash's TCP output could lead to a man-in-the-middle (MitM) attack in “client” mode, as hostname verification in TCP output was not being performed when the ssl_verification_mode => full was set.
CVE-2025-20215 1 Cisco 2 Webex, Webex Meetings 2026-04-15 5.4 Medium
A vulnerability in the meeting-join functionality of Cisco Webex Meetings could have allowed an unauthenticated, network-proximate attacker to complete a meeting-join process in place of an intended targeted user, provided the requisite conditions were satisfied. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed. This vulnerability existed due to client certificate validation issues. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by monitoring local wireless or adjacent networks for client-join requests and attempting to interrupt and complete the meeting-join flow as another user who was currently joining a meeting. To successfully exploit the vulnerability, an attacker would need the capability to position themselves in a local wireless or adjacent network, to monitor and intercept the targeted network traffic flows, and to satisfy timing requirements in order to interrupt the meeting-join flow and exploit the vulnerability. A successful exploit could have allowed the attacker to join the meeting as another user. However, the Cisco Product Security Incident Response Team (PSIRT) is not aware of any malicious use of the vulnerability that is described in this advisory.
CVE-2025-22874 2026-04-15 7.5 High
Calling Verify with a VerifyOptions.KeyUsages that contains ExtKeyUsageAny unintentionally disabledpolicy validation. This only affected certificate chains which contain policy graphs, which are rather uncommon.
CVE-2024-6001 1 Lenovo 1 Accessories And Display Manager 2026-04-15 8.1 High
An improper certificate validation vulnerability was reported in LADM that could allow a network attacker with the ability to redirect an update request to a remote server and execute code with elevated privileges.
CVE-2024-47258 2026-04-15 8.1 High
2N Access Commander version 2.1 and prior is vulnerable in default settings to Man In The Middle attack due to not verifying certificates of 2N edge devices. 2N has currently released an updated version 3.3 of 2N Access Commander, with added Certificate Fingerprint Verification. Since version 2.2 of 2N Access Commander (released in February 2022) it is also possible to enforce TLS certificate validation.It is recommended that all customers update 2N Access Commander to the latest version and use one of two mentioned practices.
CVE-2024-43107 2026-04-15 7.2 High
Improper Certificate Validation (CWE-295) in the Gallagher Milestone Integration Plugin (MIP) permits unauthenticated messages (e.g. alarm events) to be sent to the Plugin. This issue effects Gallagher MIPS Plugin v4.0 prior to v4.0.32, all versions of v3.0 and prior.
CVE-2024-12174 1 Tenable 1 Security Center 2026-04-15 2.7 Low
An Improper Certificate Validation vulnerability exists in Tenable Security Center where an authenticated, privileged attacker could intercept email messages sent from Security Center via a rogue SMTP server.
CVE-2024-21543 2026-04-15 7.1 High
Versions of the package djoser before 2.3.0 are vulnerable to Authentication Bypass when the authenticate() function fails. This is because the system falls back to querying the database directly, granting access to users with valid credentials, and eventually bypassing custom authentication checks such as two-factor authentication, LDAP validations, or requirements from configured AUTHENTICATION_BACKENDS.
CVE-2025-53869 1 Brother 1 Multiple Mfps 2026-04-15 3.7 Low
Multiple MFPs provided by Brother Industries, Ltd. does not properly validate server certificates, which may allow a man-in-the-middle attacker to replace the set of root certificates used by the product with a set of arbitrary certificates.
