DescriptionThe Product Designer for WooCommerce WordPress | Lumise plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.1.2 via the process_checkout function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. The lumise_security nonce required to reach the vulnerable /?lumise=cart endpoint is freely obtainable by any unauthenticated visitor via the /?lumise=ajax action=init handler, making this exploitable with no prior access or credentials.
