description

Hermes Agent's webhook gateway can resolve a colon-containing route name to a different route when determining toolset permissions. An attacker holding the target webhook HMAC may obtain toolsets assigned to a higher-privileged route.

mitigation

Disallow colons in webhook route names and review existing routes for ambiguous prefix relationships. Restrict access to webhook HMAC secrets and rotate them where exposure is suspected; no fixed version is recorded.
