Mattermost Missing Authentication for Critical Function

Quick fix

GHSA-j5jw-m2ph-3jjf — github.com/mattermost/mattermost/server/v8: upgrade to the fixed version with the command below.

go get github.com/mattermost/mattermost/server/v8@v10.5.2

Details

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.
