Validação incorreta de origem (Origin Validation Error)

A aplicação falha em validar corretamente a origem (origem HTTP, domínio, referência) de requisições ou recursos, permitindo que um atacante simule estar vindo de uma origem confiável. Isso quebra mecanismos de segurança como CORS, CSRF e validações de referência, abrindo porta para ataques cross-site.

Ejemplo

Um banco implementa proteção CSRF verificando se o header `Origin` é igual a `banco.com.br`, mas não valida subdomínios. Um atacante consegue fazer requisições de `falso.banco.com.br` que passam na validação e transferem dinheiro da vítima.

Cómo mitigar

Valide a origem de forma rigorosa usando whitelist explícita (não apenas prefixos ou sufixos), implemente tokens CSRF anti-previsíveis, configure CORS corretamente evitando `Access-Control-Allow-Origin: *`, e use SameSite cookies quando possível.
