CVE-2026-35670
OpenClaw: Synology Chat reply delivery could be rebound through username-based user resolution.
Description
## 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`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `7ade3553b74ee3f461c4acd216653d5ba411f455` ## 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.
