CVE-2024-52798

path-to-regexp turns path strings into a regular expressions. In certain cases, path-to-regexp will output a regular expression that can be exploited to cause poor performance. The regular expression that is vulnerable to backtracking can be generated in the 0.1.x release of path-to-regexp. Upgrade to 0.1.12. This vulnerability exists because of an incomplete fix for CVE-2024-45296.

Weakness
