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

The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.

Affected Software

Extended Description

	  Attackers can create crafted inputs that
	  intentionally cause the regular expression to use
	  excessive backtracking in a way that causes the CPU
	  consumption to spike.
