Expressão regular com complexidade exponencial (ReDoS)

A aplicação usa uma regex com padrão mal construído que, em certos inputs, força o engine a testar bilhões de combinações antes de confirmar a rejeição. Isso consome CPU até paralisar o serviço, já que o tempo cresce exponencialmente com o tamanho da entrada.

Example

Uma validação de email como `(a+)+b` aplicada a uma string longa sem 'b' no final faz o engine tentar todas as combinações possíveis de agrupamento de 'a's antes de falhar — um input de 50 caracteres pode levar minutos para processar.

How to mitigate

Use ferramentas como `redos`, `regex-checker` ou testes de desempenho para validar regexes antes do deploy. Para casos simples (email, URL), prefira validadores específicos em vez de regex; se usar regex, limite o tamanho da entrada e adicione timeouts no engine.
