OpenClaw's Synology Chat dmPolicy=allowlist failed open on empty allowedUserIds, allowing unauthorized agent dispatch
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
