Apache Tomcat: Apache Tomcat: Authentication bypass via client certificate misconfiguration

A flaw was found in Apache Tomcat where OCSP-based certificate validation may incorrectly soft-fail during CLIENTCERT authentication, even when soft-fail is disabled, under certain FFM-related execution paths. This can result in client certificates being accepted despite failed or unverifiable...

PT-2026-43368

Name of the Vulnerable Software and Affected Versions IBM HTTP Server version 8.5 IBM HTTP Server version 9.0 Description Remote code execution and denial of service are possible in configurations that utilize TLS mutual authentication, also known as client authentication, which is a process wher...

IBM HTTP Server 代码注入漏洞

IBM HTTP Server is an enterprise-level web server software developed by International Business Machines IBM. Versions 8.5 and 9.0 of IBM HTTP Server contain code injection vulnerabilities. These vulnerabilities stem from configurations involving TLS mutual authentication, which may lead to remote...

OSEC-2026-07 TLS-server does insufficient client certificate checks (missing KeyUsage and ExtendedKeyUsage validation)

The TLS server implementation does not validate the KeyUsage and ExtendedKeyUsage extensions of client certificates when mutually authenticated TLS is requested. This can lead to impersonation with a certificate issued to a server. Scenario An operations engineer enables mTLS on the admin endpoin...

PT-2026-42203

Name of the Vulnerable Software and Affected Versions OCaml-TLS versions prior to 2.1.0 Description The server implementation fails to properly validate the KeyUsage and ExtendedKeyUsage extensions of certificates provided by clients during mutual TLS mTLS authentication. This allows an attacker ...

CVE-2026-44700

Elixir WebRTC is an Elixir implementation of the W3C WebRTC API. Prior to 0.15.1 and 0.16.1, missing DTLS peer certificate fingerprint validation in the DTLS client active role removes one side of WebRTC's mutual authentication. The bug is not independently exploitable for media interception in...

CVE-2026-23998 Fleet has a Windows MDM management endpoint authentication bypass

Fleet is open source device management software. Prior to version 4.81.0, a vulnerability in Fleet’s Windows MDM management endpoint could allow requests to be processed without proper client certificate validation. In certain circumstances, this could allow an attacker to impersonate an enrolled...

GHSA-C839-4QXR-J4X3 Incus has an OVN TLS Verification that Accepts Peer-Supplied Roots

Summary Broken TLS validation logic in the OVN database connection logic could allow connections to an attacker's OVN database. OVN uses mTLS for authentication, so the attacker cannot actually perform a full man in the middle attack as they won't be able to authenticated with the real OVN...
