Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The School Management System for Wordpress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the mj_smgt_user_avatar_image_upload() function in all versions up to, and including, 91.5.0. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The School Management System WordPress plugin has an arbitrary file upload vulnerability in the mj_smgt_user_avatar_image_upload() function due to missing file type validation. Unauthenticated attackers can upload arbitrary files, potentially including PHP shells, leading to remote code execution.

MitigationUpdate the plugin to a patched version immediately. If no patch exists, disable the plugin or block unauthenticated access to the upload endpoint via WAF while awaiting a fix.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if School Management System plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'School Management System' or 'Dasinfomedia School Management System'. Note the installed version from the plugin version column.
    Affected if The plugin is installed and the version is below 92.0.0 (e.g., 91.x.x or earlier)
  2. Verify plugin version via file inspection
    Access the plugin directory via FTP or file manager (wp-content/plugins/school-management-system/) and open the main plugin file (e.g., school-mgmt.php) to read the Version header in the plugin comment block.
    Affected if The Version field shows a number lower than 92.0.0
  3. Confirm the vulnerable upload function exists
    Search the plugin files for the function 'mj_smgt_user_avatar_image_upload' in the includes or admin folders, or look for files handling avatar/image uploads.
    Affected if The function exists in the codebase, indicating the vulnerable code path is present
  4. Test unauthenticated access to upload endpoint
    Use a tool like curl to send a POST request to the upload endpoint (commonly at wp-admin/admin-ajax.php?action=mj_smgt_user_avatar_image_upload or similar) without providing authentication cookies.
    Affected if The endpoint responds without requiring login, allowing unauthenticated file upload attempts

If the School Management System plugin is installed at a version below 92.0.0 and the upload endpoint accepts unauthenticated requests, the environment is affected by this CVE.
