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 YayExtra – WooCommerce Extra Product Options plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the handle_upload_file function in all versions up to, and including, 1.3.7. 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 YayExtra WordPress plugin for WooCommerce contains an arbitrary file upload vulnerability in the handle_upload_file function. The function lacks proper file type validation, allowing unauthenticated attackers to upload any file type to the server, potentially achieving remote code execution.

MitigationUpdate the plugin to version 1.3.8 or later which contains the security fix. If no update is available, disable the plugin immediately and implement web application firewall rules to block suspicious file uploads.

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. Verify YayExtra plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'YayExtra - Extra Options for WooCommerce' or check the /wp-content/plugins/ directory for a folder containing 'yayextra' in the name
    Affected if The YayExtra plugin is present on the WordPress site
  2. Check installed plugin version
    In WordPress admin, click on the YayExtra plugin to view its details and locate the version number, or inspect the main plugin file (usually yayextra.php) and look for the 'Version:' header in the plugin comments
    Affected if The version is lower than 1.3.8 (the fixed version)
  3. Confirm upload functionality is exposed
    Examine the handle_upload_file function in the plugin code (typically in includes/ or classes/ folder) to verify the endpoint is accessible without authentication. Test by submitting a request to the upload endpoint without credentials
    Affected if The upload endpoint does not require authentication or proper file type validation
  4. Inspect uploads directory for suspicious files
    Check /wp-content/uploads/ and subdirectories for recently created files with dangerous extensions such as .php, .phtml, .phar, .exe, or .js that were uploaded without legitimate cause
    Affected if Unexpected executable or script files exist in upload directories that were not intentionally placed there

A site is affected if the YayExtra plugin is installed with a version lower than 1.3.8 and the upload functionality is exposed without proper validation.
