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.
-
Identify if WooCommerce License Manager is installedCheck your WordPress plugins directory (wp-content/plugins/) for a folder named 'woocommerce-license-manager' or 'license-manager-for-woocommerce', or query the WordPress database: SELECT plugin FROM wp_options WHERE option_name = 'active_plugins' LIKE '%license%';Affected if The plugin folder exists in plugins directory or the plugin is listed in active WordPress plugins
-
Determine the installed plugin versionCheck the main plugin file (usually license-manager.php or class-license-manager.php) for the 'Version' header, or look in WordPress admin under Plugins > Installed PluginsAffected if Version is 7.0.6 or lower (the vulnerability affects versions up to and including 7.0.6)
-
Inspect the uploads directory for suspicious filesCheck wp-content/uploads/ and subdirectories for .php files using: find /path/to/wp-content/uploads -name '*.php' -type fAffected if Any unexpected PHP files are found in the uploads directory, especially with random or suspicious names (e.g., shell.php, backdoor.php)
-
Review access controls on upload endpointsExamine the plugin source code for the upload handler function - look for files like class-ajax.php or class-upload.php and verify if there is nonce verification or capability checks before processing uploadsAffected if The upload functionality lacks nonce verification, capability checks, or file type validation (no restriction on .php files)
-
Check web server access logs for upload attemptsReview Apache/Nginx access logs for POST requests to the plugin's upload endpoint (search for requests to /wp-admin/admin-ajax.php?action=lm_upload or similar)Affected if Unauthenticated POST requests to upload endpoints are present in logs, especially those containing suspicious filenames
A user is affected if WooCommerce License Manager version 7.0.6 or lower is installed and the upload functionality is exposed without proper restrictions, or if suspicious PHP files exist in the uploads directory.

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 dataImmediately upgrade to a patched version of WooCommerce License Manager beyond 7.0.6. If no patch is available, disable the plugin or implement web server-level restrictions to block PHP file uploads in the uploads directory.
