Detailed vulnerability description
The vulnerability allows a remote attacker to bypass authentication for protected channel routes.
The vulnerability exists due to authentication bypass by alternate name in gateway plugin route auth protection for /api/channels paths when processing encoded dot-segment traversal path variants that plugin handlers normalize. A remote attacker can send a specially crafted request to bypass authentication for protected channel routes.
Exploitation requires plugin handlers to decode or canonicalize the incoming path and then route it to /api/channels handlers.
