What is CVE-2026-56738?

An SQL injection vulnerability exists in phpMyFAQ due to insufficient input validation in the StopWords::add() method. When an authenticated administrator uses the stop-word management feature to add a stop word, it allows the submission of a crafted input directly into the SQL query without proper escaping. This flaw could permit an attacker to execute arbitrary SQL commands, potentially leading to unauthorized data manipulation or retrieval. Version 4.1.6 has addressed this issue by implementing necessary input sanitization.
