Summary
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

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
