OpenChamber vulnerabilities

Path traversal vulnerability in OpenChamber 1.11.7 in file-serving endpoints /api/fs/read, /api/fs/stat, and /api/fs/raw, allowing unauthenticated remote attackers to read arbitrary files by supplying allowOutsideWorkspace=true and an absolute path, bypassing workspace boundary check.

Unauthenticated remote code execution vulnerability in OpenChamber 1.11.7, allowing remote attackers to execute arbitrary shell commands by sending crafted POST requests to /api/fs/exec, which passes commands verbatim to Node.js spawn() without validation.

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.
