Summary
OpenClaw's Slack reaction/pin sender-policy consistency issue in non-message ingress
Details

Summary

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.

Affected Packages / Versions

  • Package: npm openclaw
  • Latest published affected version confirmed: 2026.2.24 (npm latest as of February 26, 2026)
  • Affected range: <= 2026.2.24
  • Patched version : 2026.2.25

Technical Details

  • reaction_* and pin_* handlers now route through shared sender authorization (authorizeSlackSystemEventSender).
  • Enforced checks now include:
    • DM dmPolicy / allowFrom
    • channel users allowlist enforcement for non-DM channels
    • channel-level allow checks before system-event enqueue
  • Regression coverage added for DM allow/deny and channel-user allowlist deny paths.

Fix Commit(s)

  • aedf62ac7e669a89c7b299201bf6537dc6b12e0e
  • 75dfb71e4e8b7c2feba5a8ca662f92ea840e0147

Impact

Low-severity policy-consistency issue in Slack non-message event ingress. This may introduce unexpected reaction/pin context signals from senders outside configured policy.

Release Process Note

patched_versions is pre-set to planned release 2026.2.25. Advisory published with npm release 2026.2.25.

OpenClaw thanks @tdjackey for reporting.
