Vulnerability Overview

The Five Star Restaurant Reservations WordPress plugin before 2.4.8 does not have capability and CSRF checks in the rtb_welcome_set_schedule AJAX action, allowing any authenticated users to call it. Due to the lack of sanitisation and escaping, users with a role as low as subscriber could perform Cross-Site Scripting attacks against logged in admins

Technical Analysis

REMEDIATION: Update to version 2.4.8, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
