Summary

phpMyFAQ before 4.1.5 applies inconsistent active=yes and publication-date filtering across its public FAQ API endpoints, allowing unauthenticated attackers to retrieve inactive (draft or review-only) FAQ content. Specifically, GET /api/v3.1/faq/{categoryId}/{faqId} returns the inactive FAQ title and full answer, while GET /api/v3.1/faqs/tags/{tagId} and GET /api/v4.0/faqs/tags/{tagId} return the inactive FAQ title and answer preview, disclosing non-public content.
