Database metadata disclosure via cms_content parameter injection
Published May 7, 2026 · Updated May 7, 2026
SQL injection in ChestnutCMS 1.5.10 and earlier allows remote authenticated users to disclose database metadata through a crafted template. The cms_content tag incorporates attacker-controlled template parameter data into a SQL query when the edited template is previewed or rendered. Exploitation requires backend Template Management access and template-editing permission; the published error-based payload exposes database, user, and data-directory values.
