Codificação ou escape inadequado de saída

Fraqueza em que dados de saída não são codificados ou escapados corretamente antes de serem apresentados ao usuário ou processados por outro sistema. Isso permite que caracteres especiais (como <, >, aspas, Unicode) sejam interpretados como código em vez de dados literais, facilitando injeção de scripts, SQL ou outros ataques dependendo do contexto.

Exemplo

Um site que exibe um comentário do usuário sem escape HTML: se alguém enviar '<script>alert("XSS")</script>', o navegador executa o script em vez de mostrar o texto como comentário. Ou um app que insere entrada do usuário direto em comando SQL sem escape, permitindo SQL injection.

Como mitigar

Escape ou codifique a saída conforme o contexto de destino: use funções nativas de escape HTML para web (ex: `htmlspecialchars()` em PHP), prepared statements com placeholders para SQL, e bibliotecas estabelecidas como OWASP Encoder. Nunca confie em input do usuário — trate toda saída como potencialmente perigosa.
