Fat Free CRM anterior a la 0.26.0 contiene una vulnerabilidad de referencia directa insegura a objetos que permite a los usuarios autenticados modificar o eliminar los comentarios de otros usuarios, porque CommentsController#update y #destroy usan un Comment.find sin ámbito y sin comprobaciones de autorización. Los atacantes pueden enviar solicitudes PUT o DELETE a /comments/:id con IDs secuenciales enumerables para editar o eliminar comentarios sobre contactos, cuentas, leads y oportunidades que pertenecen a otros.
