A vulnerability has been found in Jupiter Theme and JupiterX Theme on WordPress (WordPress Plugin) (version now known) and classified as critical. This vulnerability affects the function jupiterx_cp_load_pane_action of the component AJAX Action Handler. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Vulnerable versions of the Jupiter (<= 6.10.1) and JupiterX (<= 2.0.6) Themes allow logged-in users, including subscriber-level users, to perform Path Traversal and Local File inclusion. In the JupiterX theme, the jupiterx_cp_load_pane_action AJAX action present in the lib/admin/control-panel/control-panel.php file calls the load_control_panel_pane function. It is possible to use this action to include any local PHP file via the slug parameter. The Jupiter theme has a nearly identical vulnerability which can be exploited via the mka_cp_load_pane_action AJAX action present in the framework/admin/control-panel/logic/functions.php file, which calls the mka_cp_load_pane_action function.
