CVSS 7.5 HIGH
A flaw was found in path-to-regexp. A remote attacker could exploit this vulnerability by providing specially crafted input that generates a regular expression with multiple sequential optional groups. This leads to an exponential growth in the generated regular expression, causing a Denial of Service (DoS) due to excessive resource consumption.
