A Regular Expression Denial of Service (ReDoS) flaw was found in stealjs steal 2.2.4 via the input variable in main.js.

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.
