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.
