{"id":"CVE-2026-2127","state":"PUBLISHED","title":"SiteOrigin Widgets Bundle <= 1.70.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Shortcode Execution","description":"The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to unauthorized arbitrary shortcode execution in all versions up to, and including, 1.70.4. This is due to a missing capability check on the `siteorigin_widget_preview_widget_action()` function which is registered via the `wp_ajax_so_widgets_preview` AJAX action. The function only verifies a nonce (`widgets_action`) but does not check user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes by invoking the `SiteOrigin_Widget_Editor_Widget` via the preview endpoint. The required nonce is exposed on the public frontend when the Post Carousel widget is present on a page, embedded in the `data-ajax-url` HTML attribute.","publishedAt":"2026-02-18T08:26:04.127Z","updatedAt":"2026-04-08T17:19:28.822Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["gpriday SiteOrigin Widgets Bundle"],"affected":[{"vendor":"gpriday","product":"SiteOrigin Widgets Bundle","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.70.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/bf92c64b-ca76-4af7-a1e4-585a60b03153?source=cve","https://plugins.trac.wordpress.org/browser/so-widgets-bundle/tags/1.70.4/base/inc/actions.php#L6","https://plugins.trac.wordpress.org/browser/so-widgets-bundle/tags/1.70.4/base/inc/actions.php#L75","https://plugins.trac.wordpress.org/browser/so-widgets-bundle/tags/1.70.4/widgets/post-carousel/post-carousel.php#L590","https://plugins.trac.wordpress.org/browser/so-widgets-bundle/tags/1.70.4/widgets/editor/editor.php#L120","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3460939%40so-widgets-bundle%2Ftrunk&old=3434183%40so-widgets-bundle%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2127.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2127","state":"PUBLISHED","datePublished":"2026-02-18T08:26:04.127Z","dateUpdated":"2026-04-08T17:19:28.822Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-06T19:20:41.302Z"},"containers":{"cna":{"title":"SiteOrigin Widgets Bundle <= 1.70.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Shortcode Execution","descriptions":[{"lang":"en","value":"The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to unauthorized arbitrary shortcode execution in all versions up to, and including, 1.70.4.
