{"id":"CVE-2021-4368","state":"PUBLISHED","title":"Frontend File Manager <= 18.2 - Authenticated Settings Change leading to Arbitrary File Upload","description":"The Frontend File Manager plugin for WordPress is vulnerable to Authenticated Settings Change in versions up to, and including, 18.2. This is due to lacking capability checks and a security nonce, all on the wpfm_save_settings AJAX action. This makes it possible for subscriber-level attackers to edit the plugin settings, such as the allowed upload file types.  This can lead to remote code execution through other vulnerabilities.","publishedAt":"2023-06-07T01:51:38.452Z","updatedAt":"2026-04-08T17:15:11.119Z","severity":{"score":9.9,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["nmedia Frontend File Manager Plugin"],"affected":[{"vendor":"nmedia","product":"Frontend File Manager Plugin","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"18.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/adb1d8b0-b1d6-40df-b591-f1062ee744fb?source=cve","https://blog.nintechnet.com/wordpress-frontend-file-manager-plugin-fixed-multiple-critical-vulnerabilities/","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=2554359%40nmedia-user-file-uploader&new=2554359%40nmedia-user-file-uploader&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T19:49:23.890Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/4xxx/CVE-2021-4368.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2021-4368","state":"PUBLISHED","datePublished":"2023-06-07T01:51:38.452Z","dateUpdated":"2026-04-08T17:15:11.119Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2023-06-06T13:09:06.280Z"},"containers":{"cna":{"title":"Frontend File Manager <= 18.2 - Authenticated Settings Change leading to Arbitrary File Upload","descriptions":[{"lang":"en","value":"The Frontend File Manager plugin for WordPress is vulnerable to Authenticated Settings Change in versions up to, and including, 18.2.
