GHSA-g839-vp47-wgh8: Duplicate Advisory: OpenClaw's Slack reaction/pin sender-policy consistency issue in non-message ingress
(updated )
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-rm2p-j3r7-4x4j]. This link is maintained to preserve external references.
Original Description
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.
