Falhas do tipo CWE-1333

Expressão regular com complexidade exponencial (ReDoS)

A aplicação usa uma regex que, em certos padrões de entrada, causa backtracking excessivo e consome CPU de forma exponencial. O motor regex tenta múltiplas combinações de correspondência antes de falhar ou suceder, podendo travar a aplicação ou deixá-la lenta demais para responder.

Exemplo

Um validador de email com regex como `(a+)+b` recebe a string `aaaaaaaaaaaaaaaaaaaaX` (sem o caractere final esperado). O motor testa todas as combinações de agrupamento do `a` repetido, levando tempo exponencial em relação ao tamanho da entrada.

Como mitigar

Use bibliotecas de parsing ou validação especializadas em vez de regex complexas (ex: bibliotecas de email ou URL). Se regex for necessária, teste com inputs longos malformados, limpe a entrada antes, ou use engines regex com proteção contra backtracking (como a do Rust).
