{"id":"CVE-2026-111190","state":"PUBLISHED","title":"ARForms <= 7.2.4 - Unauthenticated Arbitrary File Upload to Remote Code Execution via X-FILENAME Header","description":"The ARForms plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 7.2.4 via its form file-upload handler. The name of the stored file is taken from an attacker-controlled request header and is not adequately restricted to safe file types, and the plugin's file-type and content-safety checks can be evaded, allowing files that contain executable PHP code to be written to a publicly accessible directory. This makes it possible for unauthenticated attackers to upload malicious files to the affected site's server, which may make remote code execution possible. Exploitation requires a published form containing a File field to be publicly accessible on the site.","publishedAt":"2026-11-11T07:26:41.208Z","updatedAt":"2026-11-12T23:57:39.522Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["n/a ARforms"],"affected":[{"vendor":"n/a","product":"ARforms","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"7.2.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/58e67f1f-1139-406a-80fb-95aeccac9436?source=cve","https://www.arformsplugin.com/documentation/changelog/"],"weaknesses":["CWE-434"],"ingestedAt":"2026-11-13T00:04:07.093Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/111xxx/CVE-2026-111190.json","commit":"b11ebad141cb1342d2d59e57e49d50b8dd082cf9","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-111190","state":"PUBLISHED","datePublished":"2026-11-11T07:26:41.208Z","dateUpdated":"2026-11-12T23:57:39.522Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-15T17:47:44.757Z"},"containers":{"cna":{"title":"ARForms <= 7.2.4 - Unauthenticated Arbitrary File Upload to Remote Code Execution via X-FILENAME Header","descriptions":[{"lang":"en","value":"The ARForms plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 7.2.4 via its form file-upload handler.
