CVE-2021-24890Public exploitNetwork attack vector

Unauthenticated PHP upload via unchecked AJAX action

Published Sep 26, 2022 · Updated May 21, 2025

Arbitrary PHP file upload in DPlugins Scripts Organizer before 3.0 allows remote attackers to write executable PHP through an AJAX request. The saveScript action accepts unauthenticated POST data without capability, CSRF, or input validation and stores php_script content under wp-content/uploads/scripts-organizer. No WordPress account is required, and requesting the generated file executes attacker-supplied PHP in the web server context.
