{"id":"CVE-2026-7537","state":"PUBLISHED","title":"MDJM Event Management <= 1.7.8.3 - Authenticated (Administrator+) Arbitrary File Upload via 'mdjm_email_upload_file' Parameter","description":"The MDJM Event Management plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.7.8.3 via the mdjm_send_comm_email function. This is due to no file type, extension, or MIME type validation being performed on uploaded files. This makes it possible for authenticated attackers, with administrator-level access and above, to upload files that may be executable, which makes remote code execution possible.","publishedAt":"2026-06-06T02:28:35.320Z","updatedAt":"2026-06-06T11:48:22.401Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["mdjm MDJM Event Management"],"affected":[{"vendor":"mdjm","product":"MDJM Event Management","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.7.8.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/42f37a41-deff-4b17-94d8-4e0fd1ce22c2?source=cve","https://plugins.trac.wordpress.org/browser/mobile-dj-manager/trunk/includes/admin/communications/comms-functions.php#L248","https://plugins.trac.wordpress.org/browser/mobile-dj-manager/tags/1.7.8.3/includes/admin/communications/comms-functions.php#L248","https://plugins.trac.wordpress.org/browser/mobile-dj-manager/trunk/includes/admin/communications/comms-functions.php#L241","https://plugins.trac.wordpress.org/browser/mobile-dj-manager/tags/1.7.8.3/includes/admin/communications/comms-functions.php#L241","https://plugins.trac.wordpress.org/browser/mobile-dj-manager/tags/1.7.8.2/includes/admin/communications/comms-functions.php#L248","https://plugins.trac.wordpress.org/browser/mobile-dj-manager/tags/1.7.8.2/includes/admin/communications/comms-functions.php#L241","https://github.com/d0n601/CVE-2026-7537","https://ryankozak.com/posts/cve-2026-7537/","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3528037%40mobile-dj-manager&new=3528037%40mobile-dj-manager&sfp_email=&sfph_mail="],"weaknesses":["CWE-434"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/7xxx/CVE-2026-7537.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-7537","state":"PUBLISHED","datePublished":"2026-06-06T02:28:35.320Z","dateUpdated":"2026-06-06T11:48:22.401Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-30T18:20:36.475Z"},"containers":{"cna":{"title":"MDJM Event Management <= 1.7.8.3 - Authenticated (Administrator+) Arbitrary File Upload via 'mdjm_email_upload_file' Parameter","descriptions":[{"lang":"en","value":"The MDJM Event Management plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.7.8.3 via the mdjm_send_comm_email function.
