A flaw has been found in NousResearch hermes-agent 0.18.0. Affected by this issue is the function _sess_nowait of the file s71.py of the component Session Management. This manipulation of the argument session_id causes authorization bypass. The attack can be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.
