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.
