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 King Addons for Elementor is installed
    Navigate to WordPress admin > Plugins, or inspect the /wp-content/plugins/king-addons directory on the server file system
    Affected if The plugin is present on the WordPress site
  2. Identify the installed version
    Check the plugin main file (e.g., king-addons.php) for the 'Version' header, or view the version in WordPress admin > Plugins > King Addons for Elementor
    Affected if The version number cannot be determined or falls within an unpatched range
  3. Check for suspicious uploaded PHP files
    Search the /wp-content/uploads/ directory and other writable directories for .php files, especially those with random names or unusual timestamps: find /wp-content/uploads/ -name '*.php' -type f
    Affected if Unexpected PHP files are found in upload directories, particularly with recent creation dates or names resembling web shells (e.g., shell.php, backdoor.php)
  4. Review access logs for file upload requests
    Examine web server access logs (Apache/nginx) for POST requests to typical upload endpoints that include the plugin's AJAX handlers or file upload routes
    Affected if Unauthenticated POST requests to upload-related endpoints are present in the logs, especially from unexpected IP addresses

A user is affected if King Addons for Elementor is installed and the version is unpatched, or if suspicious PHP files exist in upload directories indicating potential exploitation
