    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.

    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.

  3. 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.
