 "title": "Ultimate Product Catalog <= 5.4.0 - Cross-Site Request Forgery to Custom Field Definitions Update",
 "description": "The Ultimate Product Catalog plugin for WordPress is vulnerable to Cross-Site Request Forgery via the Custom Fields admin page in all versions up to, and including, 5.4.0, due to missing nonce validation in the save_custom_fields() function. This makes it possible for unauthenticated attackers to overwrite the catalog's custom field definitions through a forged request, if they can trick a site administrator into performing an action such as clicking a link. The custom fields feature must be enabled through the plugin's premium license.",
