CVE-2024-3562Network attack vector

Authenticated PHP code execution via Loop eval

Published Jun 20, 2024 · Updated Apr 8, 2026

PHP code injection in Custom Field Suite 2.6.7 and earlier allows remote authenticated users to execute arbitrary PHP code. The recursive_html() method interpolates Loop array indices into parent_tag and evaluates the resulting PHP expression without validating those indices. Contributor-level access is required; successful injection runs with the WordPress server process and permits arbitrary server-side PHP operations.
