CVE-2022-0421 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. The Five Star Restaurant Reservations WordPress plugin before 2.4.12 does not have authorisation when changing whether a payment was successful or failed, allowing unauthenticated users to change the payment status of arbitrary bookings. Furthermore, due to the lack of sanitisation and escaping, attackers could perform Cross-Site Scripting attacks against a logged in admin viewing the failed payments. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
