{"id":"CVE-2026-8692","state":"PUBLISHED","title":"Vedrixa Forms <= 1.1.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Form Structure Modification via wefb_save_form_structure AJAX Action","description":"The Vedrixa Forms – User Registration Form, Signup Form & Drag & Drop Form Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the structure of any form — adding, removing, or altering fields — by writing attacker-controlled data to the plugin's FORMS database table. The 'ajax-nonce' nonce used by this handler is injected into the public frontend via wp_localize_script(), so any authenticated user who visits a page containing a form shortcode can obtain it without any elevated access.","publishedAt":"2026-05-22T07:50:24.457Z","updatedAt":"2026-05-22T12:35:18.579Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["registrationformbuilder Vedrixa Forms – User Registration Form, Signup Form & Drag & Drop Form Builder"],"affected":[{"vendor":"registrationformbuilder","product":"Vedrixa Forms – User Registration Form, Signup Form & Drag & Drop Form Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/1b3b8a6c-1c84-4abe-ad4a-02302b04987b?source=cve","https://plugins.trac.wordpress.org/browser/vedrixa-forms-registration-builder/tags/1.1.1/admin/class-registration-form-builder-admin.php#L866","https://plugins.trac.wordpress.org/browser/vedrixa-forms-registration-builder/tags/1.1.1/includes/class-registration-form-builder.php#L174","https://plugins.trac.wordpress.org/browser/vedrixa-forms-registration-builder/tags/1.1.1/public/class-registration-form-builder-public.php#L121","https://plugins.trac.wordpress.org/browser/vedrixa-forms-registration-builder/tags/1.0.0/admin/class-registration-form-builder-admin.php#L866","https://plugins.trac.wordpress.org/browser/vedrixa-forms-registration-builder/tags/1.0.0/includes/class-registration-form-builder.php#L174","https://plugins.trac.wordpress.org/browser/vedrixa-forms-registration-builder/tags/1.0.0/public/class-registration-form-builder-public.php#L121","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3540543%40vedrixa-forms-registration-builder&new=3540543%40vedrixa-forms-registration-builder&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8692.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8692","state":"PUBLISHED","datePublished":"2026-05-22T07:50:24.457Z","dateUpdated":"2026-05-22T12:35:18.579Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-15T14:57:40.904Z"},"containers":{"cna":{"title":"Vedrixa Forms <= 1.1.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Form Structure Modification via wefb_save_form_structure AJAX Action","descriptions":[{"lang":"en","value":"The Vedrixa Forms – User Registration Form, Signup Form & Drag & Drop Form Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.1.
