MFA Enforcement Bypass Allows Unauthorized Removal of MFA for Other Users
Summary
MFA Enforcement Bypass Allows Unauthorized Removal of MFA for Other Users
Original description
The description as published by the source.
Mattermost versions 10.5.x <= 10.5.1, 9.11.x <= 9.11.9 fail to enforce MFA checks in PUT /api/v4/users/user-id/mfa when the requesting user differs from the target user ID, which allows users with edit_other_users permission to activate or deactivate MFA for other users, even if those users have not set up MFA.
