Summary
phpMyFAQ before version 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.
Risk Assessment
The risk is the potential for unauthorized full administrative takeover by a limited-privilege administrator, which could compromise the confidentiality, integrity, and availability of data and the entire application.
Recommendation
Immediately upgrade phpMyFAQ to version 4.1.5 or later, which includes a fix for this vulnerability.
Other vulnerabilities in phpMyFAQ
See all- CVE-2026-56736High
phpMyFAQ is an open source FAQ web application. A stored cross-site scripting (XSS) vulnerability in versions prior to 4.2.0-alpha allows any unauthenticated user (or low-privileged registered user) to inject arbitrary JavaScript that executes in an administrator's browser when they review or edit a user-submitted FAQ entry.
