Summary Duplicate Advisory: OpenClaw: BlueBubbles beta plugin webhook auth hardening (remove passwordless fallback) ## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-5mx2-2mgw-x8rm. This link is maintained to preserve external references. ## Original 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.
