{"id":"CVE-2026-5324","state":"PUBLISHED","title":"Brizy – Page Builder <= 2.8.11 - Unauthenticated Stored Cross-Site Scripting via FileUpload Field Value","description":"The Brizy – Page Builder plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting in all versions up to, and including, 2.8.11 This is due to a combination of missing nonce verification for unauthenticated form submissions, insufficient handling of FileUpload fields when no file is uploaded, and the reversal of security encoding via html_entity_decode() followed by unescaped output in the admin view. The submit_form() function skips nonce verification for non-logged-in users (api.php:198). The handleFileTypeFields() function fails to overwrite user-supplied values when no file is attached. While htmlentities() is applied during storage, html_entity_decode() reverses this on display (form-entries.php:79). The form-data.php template outputs FileUpload values directly in href attributes without esc_url(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the form Leads page.","publishedAt":"2026-05-02T08:27:05.238Z","updatedAt":"2026-05-04T17:51:44.700Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themefusecom Brizy – Page Builder"],"affected":[{"vendor":"themefusecom","product":"Brizy – Page Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.8.11","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/78ec499e-5edd-4f11-9090-f79868864fee?source=cve","https://plugins.trac.wordpress.org/browser/brizy/tags/2.7.24/admin/views/form-data.php#L11","https://plugins.trac.wordpress.org/browser/brizy/tags/2.7.24/admin/form-entries.php#L79","https://plugins.trac.wordpress.org/browser/brizy/trunk/admin/views/form-data.php#L11","https://plugins.trac.wordpress.org/browser/brizy/tags/2.7.24/editor/forms/api.php#L198","https://plugins.trac.wordpress.org/browser/brizy/tags/2.7.24/editor/forms/api.php#L295","https://plugins.trac.wordpress.org/changeset/3502206/brizy/trunk/admin/views/form-data.php","https://plugins.trac.wordpress.org/changeset?old_path=%2Fbrizy/tags/2.8.11&new_path=%2Fbrizy/tags/2.8.12"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5324.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5324","state":"PUBLISHED","datePublished":"2026-05-02T08:27:05.238Z","dateUpdated":"2026-05-04T17:51:44.700Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-01T13:14:12.888Z"},"containers":{"cna":{"title":"Brizy – Page Builder <= 2.8.11 - Unauthenticated Stored Cross-Site Scripting via FileUpload Field Value","descriptions":[{"lang":"en","value":"The Brizy – Page Builder plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting in all versions up to, and including, 2.8.11 This is due to a combination of missing nonce verification for unauthenticated form submissions, insufficient handling of FileUpload fields when no file is uploaded, and the reversal of security encoding via html_entity_decode() followed by unescaped output in the admin view.
