The Jeg Kit for Elementor WordPress plugin before 2.7.0 does not sanitize SVG file contents when uploaded via xmlrpc.php, leading to a cross site scripting vulnerability.

The Jeg Elementor Kit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Video Button and Countdown Widgets in all versions up to, and including, 2.6.12 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Jeg Elementor Kit plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.6.11 via the 'expireddata' and 'buildcontent' functions. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive private, pending, scheduled, and draft template data.

The Jeg Kit for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.1.1 via the enqueuescripts() method in class/dashboard/class-dashboard.php. The plugin injects a JkitDashboardOption JavaScript object containing full plugin inventory (names, versions, paths, active status), system environment details (WordPress version, PHP version, site URLs, server capabilities), and potentially third-party API credentials (Mailchimp API key via jkituserdata) as an inline script on the post.php admin page. Because this data is output without any capability check beyond post editing access, any authenticated user with Contributor-level access or above can view this sensitive configuration data by inspecting the page source. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive site configuration data, installed plugin details, and potentially third-party API keys.
