GHSA-534w-2vm4-89xr
OpenClaw's Zalo group sender allowlist bypass permits unauthorized GROUP dispatch
A missing group-sender authorization check in the Zalo plugin allowed unauthorized GROUP messages to enter agent dispatch paths in configurations intended to restrict group traffic.
Impact
When Zalo group handling was configured with allowlist-style controls, a sender not present in the intended group allowlist could still trigger agent processing through the GROUP message path.
Root Cause
Group access checks were not consistently enforced before dispatch for Zalo GROUP messages. The fix adds explicit runtime group-policy evaluation (groupPolicy, groupAllowFrom, fallback to allowFrom) and fail-closed behavior for missing provider config.
