Falha na autenticação ou verificação insuficiente de identidade

Quando um usuário, sistema ou aplicação afirma ser alguém (ou algo), o software não valida adequadamente essa identidade antes de conceder acesso ou executar ações sensíveis. O risco é claro: um atacante se passa por outra pessoa e obtém privilégios ou dados que não deveria ter.

Example

Um app que aceita um token JWT sem verificar a assinatura, confiando apenas no nome de usuário no payload. Um atacante modifica o token para elevar seu nível de acesso e o sistema acredita, pois nunca validou a autenticidade real do token.

How to mitigate

Implemente autenticação robusta: valide credenciais em backend seguro, use protocolos padrão (OAuth 2.0, SAML, Kerberos), verifique integridade de tokens (assinatura criptográfica), implemente MFA para operações críticas e nunca confie em dados do cliente sem validação no servidor.
