Detailed vulnerability description

The vulnerability allows a remote attacker to bypass authentication and access plugin channel APIs.

The vulnerability exists due to authentication bypass using an alternate path or channel in the server-http gateway auth guard for plugin channel endpoints when processing request paths that are canonicalized differently by the gateway guard and plugin handler routing. A remote attacker can send a specially crafted request path to bypass authentication and access plugin channel APIs.

Exploitation is possible when a plugin handler canonicalizes path input such that requests skipped by the gateway auth guard are interpreted as protected /api/channels/* routes.
