Auth bypass in Openclaw
CVE-2026-62205
OpenClaw versions 2026.4.12-beta.1 before 2026.6.6 contain a missing-authorization vulnerability in the MS Teams message actions feature. When the affected feature is enabled and reachable, a lower-trust caller or a configured input path can perform actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. The issue is fixed in 2026.6.6.
