OpenClaw < 2026.2.25 - Sender Policy Bypass in Slack Reaction and Pin Event Handlers
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.
