Detailsinfo

A vulnerability was found in Elegant mes Divi Plugin up to 4.27.6. It has been rated as problematic. This issue affects an unknown function of the file class-et-builder-element.php of the component Social Media Follow Module. The manipulation of the argument skype_url with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to 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. Impacted is integrity. The summary by CVE is:

The Divi theme for WordPress is vulnerable to Stored Cross-Site Scripting via the `skype_url` shortcode attribute of the Social Media Follow module in all versions up to, and including, 4.27.6. This is due to a three-part sanitization failure: (1) the `skype_url` field is not included in the `$url_options` whitelist in `class-et-builder-element.php`, so it never invokes `esc_url_raw()` during shortcode processing, (2) the render code in `SocialMediaFollowItem.php` explicitly skips `esc_url()` for Skype URLs (`! $is_skype ? esc_url( $url ) : $skype_url`), and (3) only `sanitize_text_field()` is applied, which preserves single and double quote characters allowing attribute breakout. The unsanitized value is interpolated directly into a single-quoted `href` attribute (`href='{$social_network_link_url}'`). 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 interacts with the injected element.

The advisory is shared at wordfence.com. The identification of this vulnerability is CVE-2026-3852 since 03/09/2026. The exploitation is known to be easy. The attack may be initiated remotely.
