Until a fix is available, it is recommended to disable the `nbdesigner_upload_popup_style` site option if set to `a` (Advanced Upload Popup) to prevent unauthenticated access to the vulnerable AJAX handler. Monitor vendor communications for updates and apply official patches once released.
Description
The Printcart Store – Web to Print Product Designer for WooCommerce plugin for WordPress contains a critical arbitrary file upload vulnerability in versions up to and including 2.13.2. This flaw allows unauthenticated attackers to upload attacker-controlled PHP files outside the uploads directory via a vulnerable AJAX handler when a specific site option is enabled. Exploitation leads to remote code execution.
