CVE-2026-6832

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.

Summary		(es) Hermes WebUI contiene una vulnerabilidad de eliminación arbitraria de archivos en el endpoint /api/session/delete que permite a atacantes autenticados eliminar archivos fuera del directorio de la sesión al proporcionar una ruta absoluta o un payload de salto de ruta en el parámetro session_id. Los atacantes pueden explotar identificadores de sesión no validados para construir rutas que eviten el límite de SESSION_DIR y eliminar archivos JSON escribibles en el sistema anfitrión.
