Política de segurança cross-domain permissiva com domínios não confiáveis

Ocorre quando uma aplicação web configura mecanismos de controle de acesso cross-domain (CORS, postMessage, etc.) de forma muito aberta, permitindo que domínios não confiáveis ou controlados por atacantes acessem recursos sensíveis. Isso quebra o isolamento entre origens e expõe dados ou funcionalidades que deveriam ser protegidas.

Exemplo

Um servidor configurando Access-Control-Allow-Origin: * em endpoints que retornam dados de usuário, ou aceitando comunicação postMessage de qualquer origem sem validar o remetente. Um site malicioso pode então executar JavaScript que rouba tokens, credenciais ou informações privadas do usuário.

Como mitigar

Especifique explicitamente os domínios permitidos em CORS (nunca use wildcard em produção com dados sensíveis). Valide a origem nas requisições cross-domain e implemente verificações de token/sessão robustas. Para postMessage, sempre validate event.origin antes de processar a mensagem.
