Phpmyfaq: Security Vulnerabilities
phpMyFAQ is an open source FAQ web application. Versions 4.0.14 and 4.0.15 have a stored cross-site scripting (XSS) vulnerability that allows an attacker to execute arbitrary JavaScript in an administrator’s browser by registering a user whose display name contains HTML entities. When an administrator views the admin user list, the payload is decoded server-side and rendered without escaping, resulting in script execution in the admin context. Version 4.0.16 contains a patch for the issue.

phpMyFAQ is an open source FAQ web application. In versions prior to 4.0.16, an unauthenticated remote attacker can trigger generation of a configuration backup ZIP via `POST /api/setup/backup` and then download the generated ZIP from a web-accessible location. The ZIP contains sensitive configuration files (e.g., `database.php` with database credentials), leading to high-impact information disclosure and potential follow-on compromise. Version 4.0.16 fixes the issue.

phpMyFAQ is an open source FAQ web application. Prior to version 4.0.14, an authenticated SQL injection vulnerability in the main configuration update functionality of phpMyFAQ allows a privileged user with 'Configuration Edit' permissions to execute arbitrary SQL commands. Successful exploitation can lead to a full compromise of the database, including reading, modifying, or deleting all data, as well as potential remote code execution depending on the database configuration. This issue has been patched in version 4.0.14.

phpMyFAQ is an open source FAQ web application. Versions 4.0-nightly-2025-10-03 and below do not enforce uniqueness of email addresses during user registration. This allows multiple distinct accounts to be created with the same email. Because email is often used as an identifier for password resets, notifications, and administrative actions, this flaw can cause account ambiguity and, in certain configurations, may lead to privilege escalation or account takeover. This issue is fixed in version 4.0.13.

phpMyFAQ is an open source FAQ web application. Starting no later than version 3.2.10 and prior to version 4.0.2, an attacker can inject malicious HTML content into the FAQ editor at `http[:]//localhost/admin/index[.]php?action=editentry`, resulting in a complete disruption of the FAQ page's user interface. By injecting malformed HTML elements styled to cover the entire screen, an attacker can render the page unusable. This injection manipulates the page structure by introducing overlapping buttons, images, and iframes, breaking the intended layout and functionality. Exploiting this issue can lead to Denial of Service for legitimate users, damage to the user experience, and potential abuse in phishing or defacement attacks. Version 4.0.2 contains a patch for the vulnerability.
