Summary
The Cozy Blocks – Page Builder for Gutenberg Editor & FSE with 700+ Patterns, 58 Blocks & Templates plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.2.17. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve the name, price, short description, image URL, permalink, stock status, and product type of draft, pending, private, and catalog-hidden WooCommerce products not intended to be publicly visible. The sidebarNonce value is emitted unconditionally into public page HTML by multiple block renderers with no login gate, allowing unauthenticated visitors to harvest a valid nonce and pass the only authentication check in the handler.
