CVE-2025-27538 (GCVE-0-2025-27538)

Vulnerability from cvelistv5

Published

Modified

Severity ?

2.2 (Low) - CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N

CWE

CWE-306 - Missing Authentication for Critical Function

Summary

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.
