CVE-2025-27538

CVSS v3.1

2.7

Low

VectorAV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N
Name of the Vulnerable Software and Affected Versions Mattermost versions 9.11.x through 9.11.9 Mattermost versions 10.5.x through 10.5.1
Description The issue arises from the failure to enforce MFA checks in the PUT /api/v4/users/user-id/mfa endpoint when the requesting user differs from the target user ID. This allows users with the edit other users permission to activate or deactivate MFA for other users, even if those users have not set up MFA.
Recommendations For versions 9.11.x through 9.11.9, update to a version that enforces MFA checks for the PUT /api/v4/users/user-id/mfa endpoint. For versions 10.5.x through 10.5.1, update to a version that enforces MFA checks for the PUT /api/v4/users/user-id/mfa endpoint. As a temporary workaround, consider restricting the edit other users permission to minimize the risk of exploitation.
