O _validate_input irá retornar True em casos como '1-.22/.33./44.4-55', pois ele verifica apenas os caracteres. Creio que o ideal seria aplicar um RegEx para verificar se doc atende ao padrão de CNPJ, algo como [0-9]{2}\.[0-9]{3}\.[0-9]{3}\/[0-9]{4}\-[0-9]{2}.


return f"{doc[:2]}.{doc[2:5]}.{doc[5:8]}/{doc[8:12]}-{doc[-2:]}"
