What the vulnerability does

01Description

phpMyFAQ before 4.1.5 contains a privilege escalation vulnerability in GroupController::updatePermissions that allows GROUP_EDIT administrators to grant arbitrary rights to groups without verifying they hold those rights themselves. A delegated administrator can exploit this by assigning high-value permissions to a group they belong to, inheriting those rights and escalating privileges up to full administrative control.
