    CVE-2026-114463 (GCVE-0-2026-114463)

    Vulnerability from nvd – Published: 2026-10-21 15:01 – Updated: 2026-10-21 19:25

    Title
    CVE-2026-114463
    Summary
    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.
    Severity
    No CVSS data available.
