Validação incorreta de origem em requisições cross-origin

A aplicação falha em validar corretamente a origem (domínio) de requisições HTTP, especialmente em cenários de CORS (Cross-Origin Resource Sharing) ou WebSockets. Um atacante pode contornar controles de segurança e executar ações em nome do usuário legítimo, ou acessar dados sensíveis que deveriam estar protegidos.

Example

Um banco implementa CORS permitindo qualquer origem (`Access-Control-Allow-Origin: *`) ou valida o header `Origin` de forma fraca (aceitando subdomínios descontrolados). Um site malicioso faz requisições ao banco em background enquanto o usuário está logado, roubando dados ou transferindo dinheiro.

How to mitigate

Valide a origem contra uma lista branca explícita de domínios confiáveis; implemente SameSite cookies; use tokens CSRF + verificação de origin no servidor; evite `Access-Control-Allow-Origin: *` em APIs sensíveis; valide o header `Origin` exatamente, sem wildcards ou regex permissivo.
