Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
phpMyFAQ is an open source FAQ web application. In versions 4.0.16 and below, multiple public API endpoints improperly expose sensitive user information due to insufficient access controls. The OpenQuestionController::list() endpoint calls Question::getAll() with showAll=true by default, returning records marked as non-public (isVisible=false) along with user email addresses, with similar exposures present in comment, news, and FAQ APIs. This information disclosure vulnerability could enable attackers to harvest email addresses for phishing campaigns or access content that was explicitly marked as private. This issue has been fixed in version 4.0.17.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-200

The application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

Recommended fix High confidence

phpMyFAQ 4.0.17

  1. 1. Backup your current phpMyFAQ installation and database before proceeding.
  2. 2. Download phpMyFAQ version 4.0.17 from the official source (github.com/phpmyfaq/phpmyfaq/releases or phpmyfaq.de).
  3. 3. Extract the new version and replace the existing files, preserving your configuration file (inc/data.php or config/database.php).
  4. 4. Verify the upgrade by logging into the admin panel and checking the version number.
  5. 5. Test the affected API endpoints (OpenQuestionController::list(), comment, news, and FAQ APIs) to confirm they no longer expose non-public records or email addresses.
