Controle de acesso e privilégios inadequado

Fraqueza ampla onde o software falha em implementar ou enforçar corretamente controles de acesso, permitindo que usuários acessem recursos, funções ou dados além do que deveriam. O erro está em não validar permissões adequadamente, deixando expostos dados sensíveis ou permitindo que usuários executem ações administrativas sem autorização.

Exemplo

Um endpoint de API que lista dados de outros usuários sem verificar se quem requisita tem permissão; um painel administrativo acessível diretamente via URL sem validação de role; um arquivo de backup com permissões world-readable no servidor.

Como mitigar

Implemente validação de permissões em toda operação sensível (whitelist explícita, não blacklist); use modelos de controle como RBAC ou ABAC; aplique o princípio do menor privilégio; audite regularmente as permissões de arquivos, APIs e diretórios do sistema.
