Host code execution via generated widget PHP
Published Jul 31, 2026 · Updated Jul 31, 2026
PHP code injection in Roxnor ElementsKit before 3.10.01 allows remote authenticated users to execute code through a custom widget. The Custom Widget Builder writes markup that misses its permitted echo-pattern allowlist verbatim into widget.php, then includes and executes the generated file. The path requires Elementor and a WordPress multisite subsite Administrator, granting web-process code execution despite the network's file-editing restriction.
