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.
