Poluição de Protótipo

Fraqueza que permite a um atacante modificar o protótipo de objetos JavaScript, afetando todas as instâncias presentes e futuras da aplicação. Ocorre quando código não valida ou filtra adequadamente dados que serão mesclados em objetos, permitindo injeção de propriedades maliciosas como '__proto__' ou 'constructor.prototype'.

Exemplo

Uma API REST que aceita JSON e faz merge direto em um objeto de configuração global (ex: `Object.assign(config, userInput)`) permite que um atacante envie {"__proto__.isAdmin": true} para ganhar privilégios em todos os usuários conectados.

Como mitigar

Valide e sanitize entradas antes de atribuições em objetos; use Object.create(null) para criar objetos sem protótipo; implemente blocklists explícitas para propriedades permitidas; considere bibliotecas especializadas em deep merge seguro (como lodash com opções de segurança).
