All versions of the package word-wrap are vulnerable to Regular Expression Denial of Service (ReDoS) due to the usage of an insecure regular expression within the result variable.

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.
