Cal.com es un software de programación de código abierto. Versiones anteriores a 5.9.8, una falla en el proveedor de credenciales de inicio de sesión permite a un atacante omitir la verificación de contraseña cuando se proporciona un código TOTP, obteniendo potencialmente acceso no autorizado a las cuentas de usuario. Este problema existe debido a una lógica condicional problemática en el flujo de autenticación. Esta vulnerabilidad se corrige en 5.9.8.
