{"id":"CVE-2026-6293","state":"PUBLISHED","title":"Inquiry form to posts or pages <= 1.0 - Cross-Site Request Forgery to Stored Cross-Site Scripting via 'inq_header' Parameter","description":"The Inquiry Form to Posts or Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in version 1.0. This is due to missing nonce validation on the plugin settings update handler, combined with insufficient input sanitization on all user-supplied fields and missing output escaping when rendering stored values. The settings handler fires solely on the presence of `$_POST['inq_hidden'] == 'Y'` with no call to `check_admin_referer()` and no WordPress nonce anywhere in the form or handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts via a forged request that tricks a logged-in Administrator into visiting a malicious page.","publishedAt":"2026-04-15T06:46:18.890Z","updatedAt":"2026-04-16T13:38:48.144Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["udamadu Inquiry form to posts or pages"],"affected":[{"vendor":"udamadu","product":"Inquiry form to posts or pages","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6abd3968-a8e7-4b40-bb7e-387bab10eba9?source=cve","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inq_form.php#L63","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inq_form.php#L63","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inq_form.php#L60","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inq_form.php#L60","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inq_form.php#L180","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inq_form.php#L180","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inquery_form_to_posts_or_pages.php#L139","https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inquery_form_to_posts_or_pages.php#L139"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6293.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6293","state":"PUBLISHED","datePublished":"2026-04-15T06:46:18.890Z","dateUpdated":"2026-04-16T13:38:48.144Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-14T18:01:57.897Z"},"containers":{"cna":{"title":"Inquiry form to posts or pages <= 1.0 - Cross-Site Request Forgery to Stored Cross-Site Scripting via 'inq_header' Parameter","descriptions":[{"lang":"en","value":"The Inquiry Form to Posts or Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in version 1.0.
