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...
