Falhas do tipo CWE-269

Controle de privilégios inadequado ou ausente

A aplicação falha em validar, atribuir ou manter corretamente os privilégios de um usuário ou processo, permitindo que ele acesse recursos ou execute ações além do que deveria. Isso ocorre quando o controle de acesso é ausente, inconsistente ou não é verificado em todos os pontos críticos do código.

Exemplo

Um usuário comum consegue acessar um endpoint de administração porque a aplicação não valida se ele tem permissão, ou um processo web consegue ler arquivos do sistema que deveriam estar restritos apenas ao root — em ambos os casos, o código simplesmente não conferiu os privilégios antes de executar a operação.

Como mitigar

Implemente verificações de autorização em cada operação sensível (acesso a dados, mudança de configurações, etc.), use um modelo de privilégios bem definido (RBAC, ABAC), e verifique permissões de forma centralizada — nunca confie apenas em frontend ou em ausência de validação. Mantenha auditoria de quem fez o quê e quando.
