What is CVE-2025-15488?

The Responsive Plus plugin for WordPress prior to version 3.4.3 contains a vulnerability that allows unauthenticated users to execute arbitrary shortcodes. This occurs through the update_responsive_woo_free_shipping_left_shortcode AJAX action, which fails to validate the content_rech_data parameter effectively. As a result, attackers can potentially exploit this weakness to inject malicious shortcodes, leading to unauthorized actions on the site. It’s crucial for users to update to the latest version to mitigate these risks.
