Vulnerability from github – Published: 2026-09-05 09:30 – Updated: 2026-09-05 09:30

Details

The Divi theme for WordPress is vulnerable to DOM-Based Stored Cross-Site Scripting via the image_src attribute of the et_pb_video_slider_item shortcode in all versions up to, and including, 4.27.6. This is due to the image_src field not being included in the $url_options whitelist (which only contains url, button_link, button_url), so it never receives esc_url_raw() at save time. On the server side, the value is rendered into a data-image HTML attribute using esc_attr(), which encodes double quotes as ". However, the client-side JavaScript carousel code in custom.unified.js reads this attribute using jQuery's .data('image'), which returns the browser-decoded value (with " decoded back to "). The decoded value is then concatenated directly into an HTML string and injected into the DOM via jQuery.after() without re-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 hovers over the carousel thumbnail.

Title

Divi <= 4.27.6 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting via Video Slider 'image_src' Shortcode Parameter

Summary

The Divi theme for WordPress is vulnerable to DOM-Based Stored Cross-Site Scripting via the `image_src` attribute of the `et_pb_video_slider_item` shortcode in all versions up to, and including, 4.27.6. This is due to the `image_src` field not being included in the `$url_options` whitelist (which only contains `url`, `button_link`, `button_url`), so it never receives `esc_url_raw()` at save time. On the server side, the value is rendered into a `data-image` HTML attribute using `esc_attr()`, which encodes double quotes as `"`. However, the client-side JavaScript carousel code in `custom.unified.js` reads this attribute using jQuery's `.data('image')`, which returns the browser-decoded value (with `"` decoded back to `"`). The decoded value is then concatenated directly into an HTML string and injected into the DOM via `jQuery.after()` without re-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 hovers over the carousel thumbnail.
