Technical details

The /api/containers/<id>/exec endpoint's WebSocket upgrade request does not enforce authentication checks. An unauthenticated attacker with network access, knowledge of a target container ID, and targeting an interactive shell container can establish a raw WebSocket session and execute commands. This requires network reachability and container ID disclosure but no user interaction or authentication.
