CVE-2026-32899: OpenClaw's Slack reaction/pin sender-policy consistency issue in non-message ingress
(updated )
OpenClaw Slack monitor handled reaction_* and pin_* non-message events before applying sender-policy checks consistently.
In affected versions, these events could be added to system-event context even when sender policy would not normally allow them.
