GHSA-534w-2vm4-89xr: OpenClaw's Zalo group sender allowlist bypass permits unauthorized GROUP dispatch

mediumCVSS 4.0 5.3

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.

Advisory details

From the GitHub Advisory Database (CC BY 4.0).

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.
