Aliases CVE-2026-35635
Summary OpenClaw Bypasses DM Policy Separation via Synology Chat Webhook Path Collision ## Summary Synology Chat multi-account configuration could collapse onto a shared webhook path, replacing route ownership and bypassing per-account DM policy separation. ## 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) - `980940aa58f862da4e19372597bbc2a9f268d70b` ## 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/accounts.ts now distinguishes inherited base webhook paths from explicit per-account paths. - extensions/synology-chat/src/gateway-runtime.ts now fails closed on inherited or duplicate webhook paths and registers routes without replacement. OpenClaw thanks @tdjackey for reporting.
