CVE-2016-20073Public exploitNetwork attack vector

Unauthenticated SQL injection via unescaped POST id

Published Jun 15, 2026 · Updated Jun 15, 2026

SQL injection in the affected mattkaye WordPress plugin 1.3 allows remote attackers to read database data through modal.php. The endpoint incorporates the unescaped id POST value into an SQL query, allowing injected UNION clauses to select database records. No authentication is required because modal.php is directly accessible, and the demonstrated consequence is disclosure of WordPress terms and configuration data.
