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 `enqueue_scripts()` 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 `jkit_user_data`) 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.

The Cryptocurrency Prijsvergelijking Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting in version 1.0. This is due to insufficient output escaping in the as_get_coin_shortcode() function, which renders the 'width' (and 'height') shortcode attribute directly into the style attribute of an <iframe> element without applying any escaping function such as esc_attr(). An attacker-controlled value like '100px;"onload="alert(1)" x="' terminates the style attribute prematurely and injects an arbitrary HTML attribute into the iframe tag. 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.
