{"id":"CVE-2026-3852","state":"PUBLISHED","title":"Divi <= 4.27.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Social Media Follow 'skype_url' Shortcode Parameter","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.","publishedAt":"2026-09-03T08:28:09.084Z","updatedAt":"2026-09-03T13:16:54.004Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["Elegant Themes Divi"],"affected":[{"vendor":"Elegant Themes","product":"Divi","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.27.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/bfc5d53b-272a-4b66-8460-2134087535eb?source=cve","https://www.divichangelog.com/divi-update/divi-4/version-4-27-7"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3852.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3852","state":"PUBLISHED","datePublished":"2026-09-03T08:28:09.084Z","dateUpdated":"2026-09-03T13:16:54.004Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-09T20:10:17.984Z"},"containers":{"cna":{"title":"Divi <= 4.27.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Social Media Follow 'skype_url' Shortcode Parameter","descriptions":[{"lang":"en","value":"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.
