Impact: A bad regular expression is generated any time you have multiple sequential optional groups (curly brace syntax), such as
{a}{b}{c}:z. The generated regex grows exponentially with the number of groups, causing denial of service. Patches: Fixed in version 8.4.0. Workarounds: Limit the number of sequential optional groups in route patterns. Avoid passing user-controlled input as route patterns. - References
