Hermes Agent < 0.16.0 - Sensitive File Permission Vulnerability in Store Files

CVSS 6.8 MEDIUMEPSS 0.1%CWE-276
Hermes Agent before 0.16.0 creates response_store.db and webhook_subscriptions.json with world-readable permissions (mode 0o644), exposing conversation history and HMAC secrets to local users. Attackers with local filesystem access can read these files directly to obtain sensitive data including conversation history, tool payloads, prompts, and per-route HMAC secrets.
