{"id":"CVE-2026-4388","state":"PUBLISHED","title":"Form Maker by 10Web <= 1.15.40 - Unauthenticated Stored Cross-Site Scripting via Matrix Field Text Box","description":"The Form Maker by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Matrix field (Text Box input type) in form submissions in all versions up to, and including, 1.15.40. This is due to insufficient input sanitization (`sanitize_text_field` strips tags but not quotes) and missing output escaping when rendering submission data in the admin Submissions view. This makes it possible for unauthenticated attackers to inject arbitrary JavaScript through a form submission that executes in the browser of an administrator who views the submission details.","publishedAt":"2026-04-14T02:25:48.339Z","updatedAt":"2026-04-14T14:04:52.784Z","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":["10web Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder"],"affected":[{"vendor":"10web","product":"Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.15.40","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/197449f5-9304-49df-9261-a354145fc00e?source=cve","https://plugins.trac.wordpress.org/browser/form-maker/tags/1.15.37/admin/views/FormMakerSubmits.php#L169","https://plugins.trac.wordpress.org/browser/form-maker/tags/1.15.37/admin/views/FormMakerSubmits.php#L166","https://plugins.trac.wordpress.org/browser/form-maker/tags/1.15.37/frontend/models/form_maker.php#L2352","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3501693%40form-maker%2Ftrunk&old=3492680%40form-maker%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4388.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4388","state":"PUBLISHED","datePublished":"2026-04-14T02:25:48.339Z","dateUpdated":"2026-04-14T14:04:52.784Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-18T14:09:39.621Z"},"containers":{"cna":{"title":"Form Maker by 10Web <= 1.15.40 - Unauthenticated Stored Cross-Site Scripting via Matrix Field Text Box","descriptions":[{"lang":"en","value":"The Form Maker by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Matrix field (Text Box input type) in form submissions in all versions up to, and including, 1.15.40.
