Controle de acesso e privilégios inadequado

A fraqueza ocorre quando a aplicação não valida corretamente quem pode fazer o quê, permitindo que usuários acessem recursos ou executem operações acima de seus privilégios. Isso acontece porque as verificações de autorização são ausentes, incompletas ou contornáveis, expondo dados sensíveis ou permitindo ações não autorizadas.

Example

Um usuário comum consegue listar ou modificar dados de outros usuários alterando um ID na URL (ex: /profile/123 → /profile/999) sem que o servidor valide se ele tem permissão para acessar aquele perfil. Ou um atacante executa ações administrativas porque a aplicação só verifica autenticação, não autorização.

How to mitigate

Implemente verificações de autorização em toda operação sensível: valide não apenas se o usuário está logado, mas se ele tem permissão específica para aquele recurso. Use listas de controle de acesso (ACL), roles bem definidas e princípio do menor privilégio. Teste sistematicamente tentativas de escalação e acesso lateral entre usuários.
