CVE-2026-15083Network attack vector

Information disclosure via pre-render Twig token replacement

Published Jul 10, 2026 · Updated Jul 10, 2026

Information disclosure in Drupal ECA before 2.1.20, 3.0.12, or 3.1.4 allows remote authenticated users to expose model data. The Render: Twig action performs ECA token replacement on inline Twig source before rendering, so bracket-style array access can collapse to the entire array. Exposure requires an enabled ECA model that runs this action on a data flow; disclosed data remains unchanged.
