GHSA-GW85-XP4Q-5GP9
Vulnerability from github – Published: 2026-03-03 23:03 – Updated: 2026-03-20 21:36Summary
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.
