{"schemaVersion":3,"id":"CVE-2026-3852","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-09-03T08:28:09.084Z","modified":"2026-09-03T13:16:54.004Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.4,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":6.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00261,"percentile":0.16758,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.010999999999999985,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.0025},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00261,"percentile":0.16758}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0025,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00261,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score"
