Void Tools Everything lower than v1.4.1.1022 was discovered to contain a Regular Expression Denial of Service (ReDoS).

Weakness

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

Affected Software

Name Vendor Start Version End Version
Everything Voidtools * 1.4.1.1022 (excluding)

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.
