What is CVE-2026-3595?
CVE-2026-3595 is a medium-severity missing authorization vulnerability in imprintnext Riaxe Product Customizer, published on 16 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Riaxe Product Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.2. This is due to the plugin registering a REST API route at POST /wp-json/InkXEProductDesignerLite/customer/delete_customer without a permission_callback, causing WordPress to default to allowing unauthenticated access, and the inkxe_delete_customer() callback function taking an array of user IDs from the request body and passing each one directly to wp_delete_user() without any authentication or authorization checks. This makes it possible for unauthenticated attackers to delete arbitrary WordPress user accounts, including administrator accounts, leading to complete site lockout and data loss.
