CVE-2026-88004

Traefik entrypoint header-name sanitization bypassed via request trailers

7.0 HighFix available

Traefik is an open source HTTP reverse proxy and load balancer. From 3.2.0 until 3.7.13, Traefik entrypoint defenses aliasHeadersStrategy, underscoreHeadersStrategy, and forwardedHeaders inspect req.Header but not req.Trailer, allowing an unauthenticated client to submit an aliasing or trusted header name in an HTTP/1.1 chunked trailer or an HTTP/2 trailer. When the retry or buffering middleware reads the body before the reverse proxy clones the request, the attacker-controlled trailer value reaches a backend that merges trailers into the header namespace, bypassing the documented delete or reject behavior and potentially spoofing identity or forwarded routing data. This issue is fixed in 3.7.13.

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 client can therefore smuggle a sanitized name (an aliasing spelling such as X_Auth_User, or a trusted name such as X-Forwarded-Prefix) as an HTTP/1.1 chunked trailer or an HTTP/2 trailer: reject does not return its documented 400, delete does not remove the name, and Traefik's reverse proxy forwarded the trailer to the backend — with an attacker-chosen value whenever a body-buffering middleware (the retry middleware with status codes, or the buffering middleware) reads the body before the proxy clone. Backends that merge trailers into their header namespace then act on the smuggled name. The fix stops forwarding request trailer values to the backend; the declared trailer names are still forwarded as permitted by RFC 9110 section 6.6.2.

Traefik v2 is not affected: the defect is in the custom reverse proxy introduced in v3 (pkg/proxy/httputil), and v2 uses the Go standard library's httputil.ReverseProxy, which does not forward request trailer values to the backend. Affected v3 lines from v3.2.0 through v3.7.12 include the end-of-life v3.2 through v3.6 lines, which will not receive a fix on their own line; the remedy for those users is to upgrade to v3.7.13.

Summary

Traefik's entrypoint defenses against spoofed header names — aliasHeadersStrategy / underscoreHeadersStrategy in delete or reject mode, and the forwardedHeaders handling that strips client-supplied X-Forwarded-* — scan req.Header only and never req.Trailer, although the handlers' own comments promise to cover "header and trailer". An unauthenticated client can therefore deliver the aliasing name (X_Auth_User, X.Auth.User) or the trusted name itself (X-Forwarded-Prefix, …) as an HTTP/1.1 chunked trailer or an HTTP/2 trailer: reject does not return its documented 400, delete does not remove the name, and the trailer form of an X-Forwarded-* name passes exactly where the header form is stripped. When a body-buffering middleware is in the chain (retry with status codes, or the buffering middleware — both measured), the trailer travels with an attacker-chosen value; measured end-to-end against the trailer-merging component Ubuntu 24.04 ships (pre-fix libevent, CVE-2026-63379), the header X-Forwarded-Prefix: admin is stripped and denied while the identical name as a trailer is acted upon as admin (403 → 200). On bare proxy paths only the trailer name travels (no value), bounding those deployments to name-level effects.

Details

Root cause. All four entrypoint handlers iterate req.Header only — the doc comments promise more than the code does (pkg/server/server_entrypoint_tcp.go):

// removeAliasingHeaders removes any request header and trailer whose name contains a character
// which is neither a letter, a digit, nor a dash, as such a name aliases another header name.
func removeAliasingHeaders(h http.Handler) http.Handler {
	return http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) {
		for key := range req.Header {          // ← req.Trailer is never scanned
			if isAliasingHeaderName(key) {
				delete(req.Header, key)
			}
		}
		h.ServeHTTP(rw, req)
	})
}

rejectAliasingHeaders, removeHeadersWithUnderscores and rejectHeadersWithUnderscores share the identical structure (the reject variants return 400 from the same loop). The sibling sanitization…
