AI-suggested

Until an official fix is available, restrict user roles that can upload files, and consider disabling or limiting the plugin's file upload features. Monitor for updates from the vendor and apply patches promptly once released. Avoid server configurations that treat .phar files as executable PHP if possible.

Description

The Jupiter X Core plugin for WordPress is vulnerable to limited file uploads due to missing authorization on import_popup_templates() function as well as insufficient file type validation in the upload_files() function in all versions up to, and including, 4.14.1. This makes it possible for Authenticated attackers with Subscriber-level access and above, to upload files with dangerous types that can lead to Remote Code Execution on servers configured to handle .phar files as executable PHP (e.g., Apache+mod_php), or Stored Cross-Site Scripting via .svg, .dfxp, or .xhtml files upload on any server configuration
