CVE-2026-72782Network attack vector

Authenticated secret disclosure via pre-render interpolation

Published Aug 11, 2026 · Updated Aug 11, 2026

Information disclosure in Craft CMS 4.0.0-RC1 through 4.18.1 and 5.0.0-RC1 through 5.10.5 allows remote authenticated users to read secrets. The elementId parameter expands ${ENV_VAR} references to environment variables or secret-file values before the resulting string is rendered as a sandboxed Twig template. Control-panel access and many blind error-based requests are required; exposed values can enable session forgery, privilege escalation, or credential theft.
