A vulnerability was found in mholt PapaParse up to 5.1.x. It has been classified as problematic. Affected is an unknown function of the file papaparse.js. The manipulation leads to inefficient regular expression complexity. Upgrading to version 5.2.0 is able to address this issue. The name of the patch is 235a12758cd77266d2e98fd715f53536b34ad621. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-218004.

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
Papaparse Papaparse 5.1.0 (including) 5.2.0 (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.
