phpMyFAQ before 4.1.3 contains an authentication bypass vulnerability in API v4.0 where the default empty api.apiClientToken allows unauthenticated users to create and modify FAQ entries. Attackers can send an empty x-pmf-token header to bypass token validation and inject malicious content via POST endpoints /api/v4.0/faq/create, /api/v4.0/category, and /api/v4.0/question.
