Falhas do tipo CWE-346

Validação inadequada de origem (CORS/mesma origem)

A aplicação falha em validar corretamente a origem (domain/protocolo/porta) das requisições, permitindo que código malicioso de outros domínios acesse recursos protegidos. Isso quebra a política de mesma origem do navegador e pode expor dados sensíveis ou permitir ações não autorizadas.

Exemplo

Um servidor aceita qualquer valor no header Origin sem validação, ou valida de forma fraca (ex: substring matching). Um atacante hospeda um site malicioso que, ao ser visitado, faz requisições CORS para a aplicação vulnerável e consegue ler dados da vítima autenticada.

Como mitigar

Implemente validação rigorosa de origem: compare o header Origin contra uma whitelist explícita de domínios confiáveis (nunca use wildcards), valide protocolo e porta também, e desative CORS se não for necessário. Use credenciais com cautela em requisições cross-origin (credenciais + Access-Control-Allow-Origin: * é inseguro).
