CVE-2026-24422Public exploitNetwork attack vectorHinoki check available

Unauthenticated data disclosure via unfiltered API responses

Published Jan 24, 2026 · Updated Jan 24, 2026

Information disclosure in phpMyFAQ before 4.0.17 allows remote attackers to read email addresses and non-public content via public APIs. OpenQuestionController::list() passes showAll=true to Question::getAll(), placing invisible questions and submitter emails in responses; comment, news, and FAQ APIs have similar missing filters. No account or user interaction is required, and disclosure is limited to data returned by the affected endpoints.
