CVE-2026-15323

The 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.
