{"id":"CVE-2026-15161","state":"PUBLISHED","title":"Ninja Forms - Excel Export <= 3.3.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'filter' Parameter","description":"The Ninja Forms - Excel Export plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.6. This is due to the save_filter() AJAX handler storing the raw $_POST['filter'] array into a WordPress option via update_option() without any capability check, nonce verification, or input sanitization, combined with the get_filter_row() method on the admin Excel Export screen concatenating the stored filter values (field_key, condition, value) directly into HTML attributes without esc_attr(). This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-07-17T03:43:42.577Z","updatedAt":"2026-07-17T12:00:30.287Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["SaturdayDrive Ninja Forms - Excel Export"],"affected":[{"vendor":"SaturdayDrive","product":"Ninja Forms - Excel Export","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.3.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e9ab836b-2798-43bd-b43b-8b7c7e81d42f?source=cve","https://plugins.trac.wordpress.org/browser/ninja-forms-excel-export/trunk/includes/Admin/Menus/ExcelExport.php#L236"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15161.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15161","state":"PUBLISHED","datePublished":"2026-07-17T03:43:42.577Z","dateUpdated":"2026-07-17T12:00:30.287Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-08T20:24:07.379Z"},"containers":{"cna":{"title":"Ninja Forms - Excel Export <= 3.3.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'filter' Parameter","descriptions":[{"lang":"en","value":"The Ninja Forms - Excel Export plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.6.
