Details

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

Severity ?
8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
