Versions of the package ua-parser-js from 0.7.30 and before 0.7.33, from 0.8.1 and before 1.0.33 are vulnerable to Regular Expression Denial of Service (ReDoS) via the trim() function.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.

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.
