CVE-2026-12382 Aap-gateway: missing requestheaderstoremove allows mtls bypass via subject header spoofing

A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed...

In wolfSSL before 5.2.0, a TLS 1.3 server cannot properly enforce a requirement for mutual authentication. A client can simply omit the certificateverify message from the handshake, and never present a certificate...

CVE-2026-8932

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS...

GHSA-RXRH-4J9H-XGG9 Steeltoe: TLS private keys written to /tmp with default permissions, never deleted

Summary When MySQL or PostgreSQL service bindings from VCAPSERVICES include TLS client credentials, the Connectors library writes those credentials to temporary files in Path.GetTempPath using File.CreateText. On Linux, File.CreateText creates files with mode 0644 world-readable under the process...

PYSEC-2026-575 wolfSSL Python module vulnerable to Improper Authentication

A vulnerability in the handling of verifymode = CERTREQUIRED in the wolfssl Python package wolfssl-py causes client certificate requirements to not be fully enforced. Because the WOLFSSLVERIFYFAILIFNOPEERCERT flag was not included, the behavior effectively matched CERTOPTIONAL: a peer certificate...

CVE-2026-48928

A flaw was found in Node.js. An inconsistency in how Node.js matches hostnames can be exploited by a remote attacker in multi-context mTLS mutual Transport Layer Security setups. This vulnerability allows for a trust-policy bypass, potentially leading to unauthorized access to sensitive informati...

CVE-2026-53622

A flaw was found in Traefik, an HTTP reverse proxy and load balancer. This critical vulnerability in Traefik's HTTP/3 QUIC TLS configuration selection allows unauthenticated clients to bypass router-specific mutual Transport Layer Security mTLS enforcement. When HTTP/3 is enabled and a router use...
