Codificação ou escape inadequado de saída

A aplicação falha em codificar ou fazer escape apropriado dos dados antes de enviá-los ao usuário, permitindo que caracteres especiais sejam interpretados como código (HTML, JavaScript, SQL, etc.). Isso abre brecha para injeção de payload malicioso, especialmente XSS em contextos web.

Example

Um formulário de busca que exibe o termo pesquisado sem escape: se o usuário digita '<img src=x onerror=alert(1)>', a página renderiza o JavaScript em vez de mostrar o texto como string inócua.

How to mitigate

Aplique escape contextual (HTML entity encoding para HTML, JavaScript encoding para scripts, URL encoding para parâmetros) usando bibliotecas consolidadas da sua stack (DOMPurify, OWASP ESAPI, etc.). Validar entrada é primeira linha de defesa, mas escape de saída é crítico e obrigatório.
