Falta de verificação de autorização

O software permite que um usuário acesse recursos ou execute ações sem verificar se ele tem permissão para isso. O código autentica (confirma quem é), mas não autoriza (verifica o que pode fazer). Resultado: qualquer autenticado pode fazer o que quiser — ler dados de outros usuários, deletar registros, alterar configurações.

Ejemplo

Uma API de banco de dados que autentica o cliente via token JWT, mas retorna qualquer registro solicitado sem checar se o usuário é dono do dado. Um usuário autenticado consegue consultar CPF, conta bancária e extrato de qualquer outro cliente apenas mudando um parâmetro ID na requisição.

Cómo mitigar

Implemente controle de acesso em cada operação sensível: antes de retornar um recurso, valide se o usuário autenticado tem permissão (via papel, proprietário, ou ACL). Use um padrão consistente — biblioteca de autorização, middleware ou serviço centralizado — para não deixar brechas espalhadas no código.
