Summary OpenClaw: Feishu thread history and quoted messages bypass sender allowlist ## Summary Feishu thread history and quoted messages bypass sender allowlist ## Current Maintainer Triage - Status: open - Normalized severity: medium - Assessment: Real in shipped v2026.3.28 Feishu because fetched quoted/root/thread context bypasses sender allowlists, and SECURITY.md does not exempt remote sender-allowlist bypasses. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31` ## Fix Commit(s) - `f45e5a6569aab1d58cc6de25b19f1dc4c8779b85` — 2026-03-31T19:43:54+09:00 ## Release Process Note - The fix is already present in released version `2026.3.31`. - This draft looks ready for final maintainer disposition or publication, not additional code-fix work. OpenClaw thanks @AntAISecurityLab for reporting.
