Overview
getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.
Affected versions of this package are vulnerable to Incorrect Authorization in the FlexApiController::update process. An attacker can gain full administrative control by exploiting insufficient authorization checks on the /api/v1/flex-objects/user-accounts and /api/v1/flex-objects/user-groups endpoints to change a super administrator's password or escalate privileges to the admin.super group. This is only exploitable if the attacker has an authenticated account with api.access, admin.login, and users.update permissions, but lacks api.users.write or admin.super permissions.
