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 against a path that normalizes to /, while the proxy forwards the attacker's original target byte-for-byte to the backend. Router path/prefix guards, forwardAuth path-scoped policies and the encodedCharacters hardening never see the real …

There is a medium severity vulnerability in Traefik's HTTP/3 entry points: the respondingTimeouts settings were not applied to the HTTP/3 request path. readTimeout in particular is on by default at 60s and is documented as bounding the time to read the entire request including its body, but it is enforced as a deadline on the TCP connection, which cannot reach a QUIC stream, and Traefik's HTTP/3 server was constructed with …

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, …

There is a medium severity vulnerability in Traefik's handling of request headers whose name aliases another header name. Go canonicalizes header names on dashes only, so X-Auth-User, X_Auth_User and X.Auth.User are three distinct headers to Traefik, while backends that derive variable names from header names (CGI, WSGI, PHP, NGINX, and others) collapse all of them into the same variable. A client can therefore smuggle an alias of a header that …

Insufficient clearing of the output buffer in Java-based decompressor implementations in lz4-java 1.10.0 and earlier allows remote attackers to read previous buffer contents via crafted compressed input. In applications where the output buffer is reused without being cleared, this may lead to disclosure of sensitive data. JNI-based implementations are not affected.

After an API Token exposure from an exploited trivy dependency, two new releases of litellm were uploaded to PyPI containing automatically activated malware, harvesting sensitive credentials and files, and exfiltrating to a remote API. Anyone who has installed and run the project should assume any credentials available to litellm environment may have been exposed, and revoke/rotate thema ccordingly.
