CVE-2026-86816 · Severity: info · Published 2026-10-07

WPCafe is a WordPress plugin that integrates with WooCommerce to manage cafes and restaurants. The plugin's REST API endpoints fail to enforce authentication, allowing anyone on the internet to access sensitive product information including sales counts, stock levels, and private metadata that WooCommerce normally restricts to authenticated users. This exposes business-critical inventory and sales data.
