CVE-2025-12682
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 · uneditedThe 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 confidenceThe 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm the plugin is installedLog 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 directoryAffected if The plugin directory exists on the server
-
Identify the installed versionCheck 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 listAffected if The version listed is 2.9.8 or lower (any version up to and including 2.9.8)
-
Check if the vulnerable function is accessibleInspect 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
-
Test for unrestricted .js file uploadSubmit 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 rejectionAffected 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 dataUpdate 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.
