Summary
OpenClaw: Synology Chat reply delivery could be rebound through username-based user resolution.
Details

Summary

Synology Chat reply delivery could rebind to a mutable username match instead of the stable numeric user_id recorded by the webhook event.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: < 2026.3.22
  • Fixed: >= 2026.3.22
  • Latest released tag checked: v2026.3.23-2 (630f1479c44f78484dfa21bb407cbe6f171dac87)

Release Status

The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

  • extensions/synology-chat/src/webhook-handler.ts now keeps replies bound to the stable webhook user identifier unless an explicit dangerous opt-in is enabled.
  • extensions/synology-chat/src/config-schema.ts contains the explicit dangerous opt-in seam instead of silent username rebinding.

OpenClaw thanks @nexrin for reporting.
