OpenClaw: Google Chat and Zalouser group sender allowlist bypass via policy downgrade

Summary

When only a route-level group allowlist was configured, sender policy resolution silently downgraded from allowlist to open instead of preserving the configured group policy.

Impact

Any member of an allowlisted Google Chat space or Zalouser group could interact with the bot even when the operator intended sender-level restrictions.

Affected Component

extensions/googlechat/src/monitor-access.ts, extensions/zalouser/src/monitor.ts

Fixed Versions

• Affected: <= 2026.3.24
• Patched: >= 2026.3.28
• Latest stable 2026.3.28 contains the fix.

Fix

Fixed by commit e64a881ae0 (Channels: preserve routed group policy).

OpenClaw thanks @AntAISecurityLab for reporting.
