Administrator SQL injection via unvalidated list sorting

Published Sep 17, 2026 · Updated Sep 19, 2026

SQL injection in Tribulant Software Newsletters 4.18 and earlier allows remote authenticated users to read database data via admin list sorting. Administrative list views accepted attacker-controlled sort-column and direction values for SQL ordering without restricting them to valid fields and directions. Administrator privileges are required, and exploitation can disclose private WordPress database contents and interrupt database-backed service without reported integrity impact.
