Denial of Service in axios

  • Disclosed: 29.05.2019
  • Updated: 11.10.2026 10:22

Versions of axios prior to 0.18.1 are vulnerable to Denial of Service. If a request exceeds the maxContentLength property, the package prints an error but does not stop the request. This may cause high CPU usage and lead to Denial of Service.

Recommendation

Upgrade to 0.18.1 or later.
