Summary Duplicate Advisory: BlueBubbles sender policy could match mutable conversation identifiers ## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-8j37-5w68-wj2g. This link is maintained to preserve external references. ## Original Description OpenClaw before 2026.5.7 contains a sender policy bypass vulnerability in BlueBubbles that allows participants to match allowlist entries through conversation metadata rather than stable sender identity. Attackers can influence conversation-level identifiers to receive agent responses intended for configured senders, potentially bypassing access controls.
