CVE-2024-9659Network attack vector

Unauthenticated arbitrary upload via unchecked avatar file type

Published Nov 23, 2024 · Updated Apr 8, 2026

Unrestricted file upload in Dasinfomedia School Management System for WordPress 91.5.0 and earlier allows remote attackers to upload arbitrary files. The mj_smgt_user_avatar_image_upload() function accepts avatar content without validating its file type before storing it on the server. No authentication is required, and uploaded server-executable content can result in arbitrary code execution under the web server's privileges.
