Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2024-21538
CWEhttps://cwe.mitre.org/data/definitions/1333.html

Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.

Weakness

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

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.
