Summary

The BlueBubbles webhook handler in OpenClaw versions prior to 2026.2.21 contains a passwordless fallback authentication path that allows unauthenticated webhook events in certain reverse-proxy or local routing configurations. Attackers can bypass webhook authentication by exploiting loopback/proxy heuristics.

Risk Assessment

An attacker can send unauthenticated webhook events to the BlueBubbles plugin, potentially leading to unauthorized actions. This may compromise the integrity of the communication system.

Recommendation

Update OpenClaw to version 2026.2.21 or later. Verify reverse-proxy configuration and ensure webhook authentication is enforced.
