CVE-2026-88008
Traefik: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') and Incorrect Authorization
Traefik is an open source HTTP reverse proxy and load balancer. From 2.11.26 until 2.11.57 and 3.7.13, Traefik forwards a client-supplied Connection header requesting Upgrade, the Upgrade: h2c token, and HTTP2-Settings to a shared backend. If the backend accepts h2c and returns 101 Switching Protocols, Traefik enters a raw tunnel and no longer applies routers, BasicAuth, ForwardAuth, IPAllowList, RateLimit, access logging, metrics, or tracing to later HTTP/2 requests, allowing an unauthenticated request through an unprotected route to reach protected paths on the same backend. This issue is fixed in 2.11.57 and 3.7.13.

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 forwarded to the backend. A backend that honours the h2c upgrade and answers 101 Switching Protocols puts Traefik into a raw byte tunnel that bypasses the router and the entire middleware chain (authentication, IPAllowList, rate limiting) on a shared backend. The fix stops forwarding the Upgrade: h2c token and the HTTP2-Settings header; Upgrade: websocket is unaffected. Exploitation requires a backend that upgrades h2c without validating the Connection listing; common off-the-shelf servers were not exploitable in testing.
Traefik v3.4.2 through v3.6 are end-of-life and are also affected; users on those versions must upgrade to v3.7.13.

Summary
Traefik's default HTTP reverse proxy forwards arbitrary Connection: Upgrade / Upgrade: <token> requests to the backend. Upgrade tokens are not restricted to protocols explicitly supported by Traefik.
This is exploitable when a backend accepts a non-WebSocket upgrade such as h2c and responds with 101 Switching Protocols. Traefik then switches the connection into a raw byte tunnel and stops applying the HTTP routing/middleware chain.
An attacker can abuse an unprotected router pointing to the backend to establish the tunnel, then send HTTP/2 requests to other paths on the same backend. Those requests bypass the Traefik router and are therefore not subject to middleware attached to the corresponding protected route.
For example:
/public /admin
(no auth) (BasicAuth)
| |
+----------- same backend ------+
^
|
h2c tunnel
|
attacker
This allows middleware such as BasicAuth, ForwardAuth, IPAllowList, and RateLimit to be bypassed. Requests sent over the tunnel also bypass Traefik's normal access logging, metrics, and tracing.
The core issue is unrestricted client-initiated protocol upgrades combined with loss of the HTTP routing/middleware layer after 101 Switching Protocols.
Technical Details
The default proxy implementation is pkg/proxy/httputil (the fast proxy remains experimental and is disabled by default).
The relevant request path is:
-
pkg/middlewares/forwardedheaders/forwarded_header.go(removeConnectionHeaders, ~lines 198-234)When
Connection: Upgradeis present, theUpgradeheader is preserved and forwarded downstream. There is no validation that the upgrade token iswebsocket. -
pkg/proxy/httputil/proxy.go(isWebSocketUpgrade, ~line 170)WebSocket receives special header handling through
cleanWebSocketHeaders, but this is not an allowlist. Other upgrade protocols are still passed through. -
pkg/server/service/smart_roundtripper.go(RoundTrip, ~line 56)Requests containing
Connection: Upgradeare sent to the backend over HTTP/1, allowing the backend to perform the upgrade. -
net/http/httputil.ReverseProxyWhen the backend returns
101 Switching Protocols, the reverse proxy switches to tunnel mode and copies bytes between the client and backend.
The security boundary breaks at this point.
The Traefik router and middleware chain are selected only for the initial HTTP/1 request. After the backend returns 101, Traefik no longer parses the connection as HTTP requests and does not…
