CVE-2026-24422: phpMyFAQ: Public API endpoints expose emails and invisible questions
Summary Several public API endpoints return email addresses and non‑public records (e.g. open questions with isVisible=false).
Details OpenQuestionController::list() calls Question::getAll() with the default showAll=true, returning invisible questions and their emails. Similar exposures exist in comment/news/faq APIs.
PoC curl -i -H 'Accept-Language: en' \ http://192.168.40.16/phpmyfaq/api/v3.0/open-questions
Impact Privacy exposure of email addresses and non‑public content; increased risk of phishing/scraping.
Other sources
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.
