- Description
- OpenClaw versions prior to 2026.2.21 BlueBubbles webhook handler 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 the loopback/proxy heuristics to send unauthenticated webhook events to the BlueBubbles plugin.
