OpenClaw before 2026.8.1 Authentication Bypass via Access Group

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, so 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. The issue is fixed in version 2026.8.1.
