CVE-2026-7537

HIGH

MDJM Event Management <= 1.7.8.3 - Authenticated (Administrator+) Arbitrary File Upload via 'mdjm_email_upload_file' Parameter

Title source: cna

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.
