Detailsinfo

A vulnerability, which was classified as problematic, was found in dartiss Code Embed Plugin up to 2.5.1 on WordPress. This affects the function sec_check_post_fields of the component AJAX Endpoint. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. The summary by CVE is:

The Code Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom field meta values in all versions up to, and including, 2.5.1. This is due to the plugin's sanitization function `sec_check_post_fields()` only running on the `save_post` hook, while WordPress allows custom fields to be added via the `wp_ajax_add_meta` AJAX endpoint without triggering `save_post`. The `ce_filter()` function then outputs these unsanitized meta values directly into page content without escaping. 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.
