CWE-22Published: April 21, 2026· Updated: Apr 22, 2026
Official 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.
Technical Analysis
CVE-2026-6832 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.1.
