Traefik: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') and Incorrect Authorization
Summary There is a high-severity request-smuggling vulnerability in Traefik's handling of the HTTP/1.1 Upgrade mechanism. Since Traefik moved to unencrypted HTTP/2 with prior knowledge Go 1.24, a client-initiated Upgrade: h2c request header and its connection-specific HTTP2-Settings header were...

Traefik entrypoint header-name sanitization bypassed via request trailers
Summary Traefik's entrypoint defenses against spoofed trusted header names — aliasHeadersStrategy / underscoreHeadersStrategy in delete or reject mode, and the default forwardedHeaders stripping of client-supplied X-Forwarded- — scan req.Header only and never req.Trailer. An unauthenticated clien...

Traefik HTTP/3 Backend NTLM Connection Reuse
Summary Traefik's HTTP/3 request path did not initialize the connection-scoped backend transport holder that isolates connection-bound NTLM and Negotiate Kerberos authentication on the HTTP/1.1 and HTTP/2 paths. The HTTP/3 entrypoint reuses the HTTPS handler chain and reaches the same backend...

GHSA-F52W-8J3H-J724 Traefik: Rootless HTTP/1 request-target routes as "/" but is forwarded verbatim, bypassing path-scoped routing, middleware guards and access logging
Summary Traefik accepts an HTTP/1.x request whose request-target is in rootless / opaque form for example GET http:http://internal-vhost/admin HTTP/1.1. Go parses this into URL.Opaque with an empty URL.Path, so Traefik evaluates all routing, path-sanitization, middleware and access-log decisions...
