Summary

OpenClaw (npm package 'openclaw') before 2026.8.1 contains an access-control bypass in the Microsoft Teams integration. When groupPolicy is set to allowlist, a missing or unsupported configured access group produces a denied group-resolution result that is not rejected by the final message-admission check.

Risk Assessment

A Teams member who is not on the allowlist can still trigger the configured agent despite the administrator's group boundary. The impact depends on the conversations, tools, and data available to that agent.

Recommendation

Update OpenClaw to version 2026.8.1. Verify groupPolicy and access group configuration for Microsoft Teams integrations.
