OpenChamber 1.11.7 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to terminate the server process by sending a POST request to the /api/system/shutdown endpoint, which is registered before the authentication middleware in the Express route handler chain. Attackers can exploit the route registration order in bootstrap-runtime.js to reach the shutdown handler before auth middleware executes, causing denial of service to all active AI coding sessions and locking out legitimate remote users regardless of whether UI_PASSWORD is configured.
