Published Sep 11, 2023 · Updated Sep 26, 2024

Reflected XSS in WpCrunch gAppointments before 1.10.0 allows remote attackers to run script in an administrator's browser via crafted booking input. With the companion input_N[time] field blank, the booking response returns input_N[cost] into the page without sanitizing or escaping it. An administrator must interact with the crafted response, after which the script executes with that browser session's page privileges.
