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 Easy Upload Files During Checkout plugin for WordPress is vulnerable to arbitrary JavaScript file uploads due to missing file type validation in the 'file_during_checkout' function in all versions up to, and including, 2.9.8. This makes it possible for unauthenticated attackers to upload arbitrary JavaScript 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 Easy Upload Files During Checkout WordPress plugin versions up to 2.9.8 lack file type validation in the file_during_checkout function, allowing unauthenticated attackers to upload arbitrary JavaScript files. This enables remote code execution since the uploaded .js files can be executed in the browser context or potentially triggered to execute server-side.

MitigationUpdate the plugin to version 2.9.9 or later which should contain proper file type validation. If no update is available, disable the plugin or implement server-side file type validation at the web server level to block .js 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. Confirm the plugin is installed
    Log in to WordPress admin and navigate to Plugins > Installed Plugins, or inspect the file /wp-content/plugins/easy-upload-files-during-checkout/ for the presence of the plugin directory
    Affected if The plugin directory exists on the server
  2. Identify the installed version
    Check the plugin header in the main plugin file (usually easy-checkout-upload.php) for the Version field, or view the plugin details in WordPress admin plugins list
    Affected if The version listed is 2.9.8 or lower (any version up to and including 2.9.8)
  3. Check if the vulnerable function is accessible
    Inspect the plugin source code for the file_during_checkout function and verify if it is hooked to an action accessible to unauthenticated users (check for add_action hooks without capability checks)
    Affected if The file_during_checkout function is hooked without authentication requirements
  4. Test for unrestricted .js file upload
    Submit a file upload request to the checkout upload endpoint (typically at /?wc-ajax=file_during_checkout or similar) with a .js file extension and verify if the upload is accepted without rejection
    Affected if The upload endpoint accepts and stores files with .js extension

You are affected if the plugin is installed with version 2.9.8 or lower and the file upload functionality is accessible to unauthenticated users, allowing .js file uploads.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the plugin to version 2.9.9 or later which should contain proper file type validation. If no update is available, disable the plugin or implement server-side file type validation at the web server level to block .js file uploads.
