Description

Summary

In openclaw versions 2026.2.22 and 2026.2.23, the optional synology-chat channel plugin had an authorization fail-open condition: when dmPolicy was allowlist and allowedUserIds was empty/unset, unauthorized senders were still allowed through to agent dispatch.

This is assessed as medium severity because it requires channel/plugin setup and Synology sender access, but can still trigger downstream agent/tool actions.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: >= 2026.2.22, <= 2026.2.23
  • Latest published affected version at patch time: 2026.2.23
  • Planned patched version: 2026.2.24

Details

Root cause was a policy mismatch across plugin code paths:

  1. Default resolved DM policy was allowlist.
  2. Empty allowedUserIds was treated as allow-all.
  3. Webhook auth in allowlist mode depended on that helper.

Result: allowlist with empty list behaved like open access for inbound Synology senders.
