Description (CNA)
Hermes Agent 0.16.0 prior to 0.17.0 contains an improper path restriction vulnerability that allows attackers who can influence ingested message content to overwrite the credential store by bypassing sensitive-path guards that excluded the auth.json file. Attackers can craft malicious messages directing the agent's file-write tooling to overwrite the credential store without triggering any path-based protection, enabling credential tampering or unauthorized access.
