CVE-2026-11601
WPCafe <= 3.0.19 - Missing Authorization to Unauthenticated Arbitrary Email Notification Flow Read/Create/Update/Delete
Description
The WPCafe – Restaurant Menu, Online Food Ordering & Table Booking System plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.0.19. 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 read, create, update, clone, and delete email notification flows, including overwriting the default reservation confirmation, cancellation, and admin alert emails with attacker-controlled content sent from the site's legitimate address, or destroying reservation notification flows entirely. The vulnerable endpoints are active by default on every WPCafe installation without any configuration requirement, as the Email_Automation_Service_Provider::is_enable() method unconditionally returns true and the plugin ships with five pre-configured default email flows upon activation.
