CVE CVE-2021-24965
CVSS 6.4 (Medium)
Publicly Published December 21, 2021
Last Updated January 24, 2023
Researcher Krzysztof Zając - CERT PL


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
