Controle de acesso e privilégios inadequado

A aplicação não valida ou não implementa corretamente as permissões necessárias para acessar recursos sensíveis, permitindo que usuários realizem operações além do seu nível de privilégio autorizado. Isso pode expor dados confidenciais, modificar informações críticas ou comprometer a integridade do sistema.

Ejemplo

Um usuário comum consegue acessar diretamente uma rota administrativa (/admin/users) porque o backend não verifica se ele é administrador antes de executar a ação, apenas confiando que não tentaria; ou um processo de aplicação roda como root quando precisaria rodar como usuário não-privilegiado, ampliando o impacto de qualquer falha.

Cómo mitigar

Implemente validação de privilégios em todas as operações sensíveis (verificar permissões no servidor, nunca só no cliente), use princípio do menor privilégio (processos e contas com permissões mínimas necessárias), e mantenha matriz de controle de acesso (RBAC ou ABAC) consistente e auditada.
