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 Super Backup & Clone - Migrate for WordPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation and a missing capability check on the ibk_restore_migrate_check() function in all versions up to, and including, 2.3.3. 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 Super Backup & Clone - Migrate for WordPress plugin versions up to 2.3.3 contains an unauthenticated arbitrary file upload vulnerability in the ibk_restore_migrate_check() function. The function lacks both capability checks (allowing unauthenticated access) and file type validation, enabling attackers to upload arbitrary files including malicious PHP scripts that can lead to remote code execution.

MitigationUpdate the plugin to the latest version immediately. If no patch is available, disable and remove the plugin. Consider reviewing the server for any previously uploaded malicious files.

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 Super Backup & Clone plugin is installed
    Log into the WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'Super Backup & Clone - Migrate' in the list.
    Affected if The plugin appears in the installed plugins list
  2. Determine the installed plugin version
    In the plugins list, view the details of 'Super Backup & Clone - Migrate' to find the version number. Alternatively, check the plugin header in the main plugin PHP file via file manager or FTP.
    Affected if Version is 2.3.3 or lower
  3. Locate the vulnerable function in plugin files
    Access the plugin directory via FTP or file manager and search the plugin files for the string 'ibk_restore_migrate_check'. This function should exist in the affected versions.
    Affected if The function ibk_restore_migrate_check is found in the plugin code without additional authorization checks nearby
  4. Check for suspicious uploaded files
    Search the wp-content directory, particularly the uploads folder and the plugin directory itself, for unexpected PHP files or other unrecognized files that may have been uploaded.
    Affected if Unexpected PHP files or scripts are found in the uploads folder or plugin directory

If the plugin is installed at version 2.3.3 or lower and contains the unprotected ibk_restore_migrate_check function, the environment is affected by this vulnerability.
