CVE-2024-4004 is a newly discovered Stored Cross-Site Scripting (XSS) vulnerability in the widely used WordPress plugin Advanced Cron Manager. This plugin, essential for managing WP Cron events and schedules, offers extensive functionality to WordPress site administrators. It allows them to view, search, execute, add, pause, and delete scheduled tasks, as well as customize PHP cron events. With over 30,000 installations, Advanced Cron Manager provides a streamlined approach to scheduling but, unfortunately, also introduces a vulnerability exploitable by users with access to the admin panel. This vulnerability allows attackers to inject malicious JavaScript code into the Cron Manager’s settings, potentially leading to a backdoor on the site.
