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

O aplicativo web recebe entrada do usuário e a exibe na página sem sanitizar tags HTML/JavaScript, permitindo que um atacante injete scripts maliciosos que executam no navegador da vítima. O risco é roubo de sessões, credenciais, redirecionamento para sites maliciosos ou modificação do conteúdo exibido.

Example

Um campo de busca que mostra 'Você pesquisou por: <script>alert(document.cookie)</script>' sem escapar a entrada. O script executa no navegador de quem clica no link compartilhado, vazando cookies de sessão.

How to mitigate

Sempre escapar (encode) caracteres especiais HTML (< > " &) na saída ou usar bibliotecas de sanitização robustas (DOMPurify, Bleach). Implementar Content Security Policy (CSP) para bloquear scripts inline não-autorizado como camada adicional de defesa.
