The Jupiter X Core plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 4.8.7 via the inline SVG feature.

The Jupiter X Core plugin for WordPress is vulnerable to Local File Inclusion to Remote Code Execution in all versions up to, and including, 4.8.7 via the getsvg() function. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files.
