CVE-2026-119559

OpenLiteSpeed versions through 1.9.4 are vulnerable to an authentication bypass over HTTP/3 . The root cause is that the QuicStream component inherits a verifyContext() implementation that consistently returns true. This allows unauthenticated remote attackers to evade virtual host client certifi...

CVE-2026-114656

Traefik versions prior to 2.11.58 and 3.7.13 are vulnerable to an authentication bypass caused by a logic error where negated Host matchers (e.g., !Host()) are incorrectly counted as served domains. This flaw allows unauthenticated clients to skip client-certificate checks when a router rule crea...

CVE-2026-114656 Traefik before 2.11.58 and 3.7.13 mTLS Bypass via Negated Host Matcher

Traefik before 2.11.58 and 3.7.13 contains an authentication bypass vulnerability that allows unauthenticated clients to skip client-certificate checks because negated Host matchers are counted as served domains. Attackers can reach backends protected by RequireAndVerifyClientCert when a router...

CVE-2026-75595

A flaw was found in Netty, an asynchronous, event-driven network application framework. An unauthenticated remote attacker can exploit fragmented Transport Layer Security TLS ClientHello messages to bypass the Server Name Indication SNI routing mechanism. This forces a fallback to a less secure...

GHSA-W34Q-CM8F-9C5X OpenTelemetry-Go: Log gRPC exporter ignores env TLS certs, bypassing mTLS/pinning

Summary The OTLP log gRPC exporter loads TLS settings from environment variables but does not apply them when creating gRPC transport credentials. Operators who rely on OTELEXPORTEROTLPLOGSCERTIFICATE, OTELEXPORTEROTLPCERTIFICATE, or related client certificate variables for CA pinning or mTLS get...
