The package terser before 4.8.1, from 5.0.0 and before 5.14.2 are vulnerable to Regular Expression Denial of Service (ReDoS) due to insecure usage of regular expressions.
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.
