Medium (5.3) in openclaw openclaw. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in openclaw 2026.2.25.
OpenClaw versions prior to 2026.2.25 fail to consistently apply sender-policy checks to reaction_* and pin_* non-message events before adding them to system-event context. Attackers can bypass configured DM policies and channel user allowlists to inject unauthorized reaction and pin events from restricted senders.
