Codificação ou escaping inadequado de saída

Ocorre quando a aplicação não codifica ou escapa corretamente dados que serão exibidos ou processados em contextos que interpretam caracteres especiais (HTML, JavaScript, SQL, URLs, etc.). Sem essa proteção, caracteres maliciosos passam intactos e podem ser interpretados como código, causando injeção ou execução não autorizada.

Ejemplo

Uma página web que exibe um comentário de usuário sem escapar tags HTML: se o atacante injeta '<script>alert(1)</script>', o navegador executa o script em vez de exibir o texto como literal. Ou um parâmetro de URL mal codificado que permite injeção SQL quando concatenado diretamente em queries.

Cómo mitigar

Sempre codifique ou escape dados de entrada antes de usá-los em contextos sensíveis: use funções nativas de encoding (ex: htmlspecialchars() em PHP, DOMPurify em JavaScript, parametrized queries em SQL). Escolha o tipo certo de encoding para cada contexto (HTML, URL, JavaScript, CSS) — não use o mesmo para todos.
