phpMyFAQ through 4.1.10 contains a missing authorization vulnerability in the MCP server faq_search tool that allows MCP clients to read restricted FAQs because Search::searchDatabase() never applies user or group permission checks. Attackers connected to the phpmyfaq:mcp:server can issue search queries to retrieve the full question and answer text of active FAQs restricted to specific users or groups.
