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.

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.

Vulnerability from cvelistv5 – Published: 2026-03-21 00:42 – Updated: 2026-03-21 03:37 X_Open Source

Title

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

Summary

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.
