## Overview

The webhook platform gateway in Nous Research Hermes Agent versions builds the session chat_id as webhook:{route_name}:{delivery_id} and re-derives the authorizing route by splitting that string, so a route name containing a ":" resolves toolset authorization to a different, higher-privileged prefix route than the one authenticated, which allows a remote attacker with the target HMAC to gain that higher-privileged route's toolsets.

## Affected

- `hermes_agent <= 2026.8.19`
