OpenClaw: Google Chat and Zalouser group sender allowlist bypass via policy downgrade
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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.
