EPSS · scored 2026-10-27

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.

  • GHSA-rm2p-j3r7-4x4jOpenClaw's Slack reaction/pin sender-policy consistency issue in non-message ingress2026-03-03ghsa · osvUS

    ### 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.
