Injeção de Script entre Sites (XSS)

Ocorre quando a aplicação insere dados não validados do usuário diretamente em páginas HTML enviadas ao navegador, permitindo que atacantes injetem código JavaScript malicioso. O navegador executa esse script com os mesmos privilégios da sessão legítima, comprometendo dados da vítima ou sua conta.

Exemplo

Um formulário de busca que exibe o termo digitado na página sem sanitização: se você buscar por '<script>alert(1)</script>', esse script será executado no navegador de quem abrir o resultado. Um atacante pode roubar cookies de sessão ou redirecionar para um site falso.

Como mitigar

Valide e escape todos os dados do usuário antes de renderizar em HTML (use funções nativas como textContent em vez de innerHTML). Para entrada de dados, liste o que é permitido (whitelist); para saída, contextualize o escape (HTML, JavaScript, URL). Use Content Security Policy (CSP) como camada adicional para restringir execução de scripts inline.
