http-proxy-middleware `router` host+path substring matching allows Host-header-driven backend routing bypass

Summary http-proxy-middleware documents router proxy-table entries as host, path, or host+path selectors, but the host+path implementation uses unanchored substring matching on attacker-controlled request metadata. As a result, a crafted Host header that is only a superstring match for a configur...

CVE-2026-50194

Steeltoe CVE-2026-50194 affects management endpoints when configured to listen on an alternate port. Versions 3.2.2–3.3.0 and 4.1.0 use the Host header to gate access instead of the socket port, enabling port-isolation bypass. Patches are in 3.4.0 and 4.2.0. If upgrading isn’t possible, apply exp...
