    phpMyFAQ before 4.1.6 contains a privilege escalation vulnerability in GroupController::updateMembers() that allows administrators with only group-management permissions to join privileged groups without verification of required rights. Attackers can add themselves to pre-existing groups holding user-management rights and immediately inherit those permissions to modify or delete user accounts.

  2. CVE-2026-66398 9.4 Critique

    phpMyFAQ before v4.1.6 contains a remote code execution vulnerability in the configuration API that allows authenticated administrators with CONFIGURATION_EDIT and ATTACHMENT_ADD privileges to write arbitrary PHP files by manipulating the upgrade.lastDownloadedPackage setting. Attackers can upload a malicious ZIP file as an attachment, point the updater configuration to its stored path, and extract it into the application root to achieve code execution as the web server user.

    phpMyFAQ before 4.1.6 fails to validate path traversal sequences in the existing_image field during category updates, allowing authenticated attackers to delete arbitrary files by exploiting insufficient sanitization in Image::delete(). Attackers can delete the database.php configuration file to disable the installation gate and access the public setup wizard to create new superadmin accounts.
