Transferência incorreta de recursos entre contextos de segurança

Ocorre quando um recurso (arquivo, memória, conexão, credencial) é movido ou compartilhado entre contextos de segurança diferentes (ex: processo privilegiado para não-privilegiado, zona confiável para não-confiável) sem validação ou proteção adequada. O recurso fica acessível a quem não deveria, ou perde suas garantias de segurança na transição.

Exemplo

Um aplicativo web salva dados sensíveis do usuário em /tmp com permissões 0644 (legível por todos), e outro processo de menor privilégio consegue ler. Ou um serviço transmite um file descriptor aberto para um cliente não autenticado, que ganha acesso ao arquivo sem passar por controles de autorização.

Como mitigar

Valide e controle explicitamente cada transferência de recurso: revise quem pode acessar o quê após a transferência, use permissões restritivas (0600), criptografe dados sensíveis em trânsito, e aplique re-autenticação ou re-autorização quando recursos cruzam limites de segurança.
