Summary
OpenClaw: Slack interactive callbacks could skip configured sender checks in some shared-workspace flows
Details

Impact

In shared Slack workspace deployments that rely on sender restrictions (allowFrom, DM policy, or channel user allowlists), some interactive callbacks (block_action, view_submission, view_closed) could be accepted before full sender authorization checks.

In that scenario, an unauthorized workspace member could enqueue system-event text into an active session. This issue did not provide unauthenticated access, cross-gateway isolation bypass, or host-level privilege escalation by itself.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable versions: <= 2026.2.24
  • Patched version: 2026.2.25 (planned next npm release)

Fix Commit(s)

  • ce8c67c314b93f570f53c2a9abc124e1e3a54715

Release Process Note

patched_versions is pre-set to the release (2026.2.25). Advisory published with npm release 2026.2.25.

Trust Model Scope Note

OpenClaw does not support adversarial multi-user isolation on a single shared gateway instance. The supported model is one trust boundary per gateway (separate gateways/hosts for mutually untrusted users). See: https://docs.openclaw.ai/gateway/security

OpenClaw thanks @tdjackey for reporting.
