CVE-2024-5503Network attack vector

Authenticated PHP execution via unsanitized layout paths

Published Jun 21, 2024 · Updated Apr 8, 2026

Local file inclusion in CodeVibrant WP Blog Post Layouts 1.1.3 and earlier allows remote authenticated users to execute uploaded PHP files. Gutenberg render callbacks and Elementor grid, list, and masonry elements use attacker-controlled layout selections in PHP include paths without restricting them to bundled templates. Contributor-level access is required, and arbitrary code execution requires a PHP-capable file already present on the server, including an uploaded file accepted as a nominally safe type.
