CVE-2026-57995 | phpMyFAQ before 4.1.5 contains a privilege escalation vulner… | CVSS 8.8 HIGH

Description

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.
