2.7 lowCVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:NCVE-2025-27538
Low (2.7) in mattermost mattermost server. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in github.com/mattermost/mattermost/server/v8 10.5.2, 8.0.0-20250314142426-c049748b8863, 9.11.10.
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.
