## Description

The Jupiter X Core plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Login widget's forgot-password link and login redirect URL settings in all versions up to, and including, 4.60.0. This is due to the URLs not being validated against allowed schemes, so javascript: URLs are output in the link's href attribute and returned to the front-end script as the redirect target. This makes it possible for authenticated attackers with contributor-level access and above, who can edit Elementor content, to inject arbitrary web scripts that execute when a user clicks the link or logs in through the form.
