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
WordPress Background Image Cropper version 1.2 contains a remote code execution vulnerability that allows unauthenticated attackers to upload arbitrary files by accessing the ups.php endpoint. Attackers can upload PHP files through the file upload form in the plugin directory to execute arbitrary code on the server.

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

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. Confirm WordPress Background Image Cropper plugin is installed
    Log into the WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'Background Image Cropper' in the list of active or inactive plugins.
    Affected if The plugin appears in the installed plugins list regardless of activation status
  2. Identify the installed plugin version
    In the WordPress plugins list, click on the plugin name or view the plugin files. Open the main plugin PHP file (usually named similarly to the plugin directory) and look for a version comment or header that states 'Version: X.X'
    Affected if The version is 1.2 exactly, or if you cannot determine the version and the plugin is present
  3. Verify the vulnerable ups.php endpoint exists
    Using a web browser or curl command, attempt to access the ups.php file directly at the expected path: /wp-content/plugins/background-image-cropper/ups.php or /wp-content/plugins/background-image-cropper/includes/ups.php
    Affected if The endpoint returns a response (200 OK) rather than a 404 Not Found error, indicating the file exists and is accessible
  4. Check for suspicious PHP files in upload directories
    Examine the wp-content/uploads directory and any plugin-specific upload folders for unexpected .php files. Use file system commands: find /path/to/wp-content/uploads -name '*.php' -mtime -30 to find recently modified PHP files.
    Affected if Any PHP files exist in upload directories, especially recently created ones, as the vulnerability allows arbitrary PHP uploads
  5. Review server access logs for ups.php access
    Check web server access logs (Apache error.log, Nginx access.log, or WordPress debug.log) for any GET or POST requests to the ups.php endpoint from IP addresses you do not recognize.
    Affected if There are any unauthenticated requests to ups.php in the logs, indicating potential exploitation attempts

You are affected if the WordPress Background Image Cropper plugin version 1.2 is installed and the ups.php endpoint is accessible, as this combination enables unauthenticated attackers to upload and execute arbitrary PHP code.
