Does this matter?
Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.
Description
OpenClaw versions 2026.4.10 before 2026.4.14 contain a missing authorization vulnerability in the Microsoft Teams SSO invoke handler that fails to apply sender allowlist checks. Attackers can bypass sender authorization by sending SSO invoke requests that are processed without proper validation, allowing unauthorized access to Teams SSO signin functionality.
