If you cannot patch yet, restrict access to the /api/session/delete endpoint to trusted users only and consider implementing additional input validation or access controls to limit session_id parameter values.
Description
Hermes WebUI contains an arbitrary file deletion vulnerability in the /api/session/delete endpoint that allows authenticated attackers to delete files outside the session directory by supplying an absolute path or path traversal payload in the session_id parameter. Attackers can exploit unvalidated session identifiers to construct paths that bypass the SESSION_DIR boundary and delete writable JSON files on the host system.
