Summary

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, for stream request bodies, maxBodyLength is bypassed when maxRedirects is set to 0 (native http/https transport path). Oversized streamed uploads are sent fully even when the caller sets strict body limits. This vulnerability is fixed in 1.15.1 and 0.31.1.

Patch / fix

  • npm axios 0.31.1, 1.15.1
  • axios axios 0.31.1, 1.15.1
  • node-axios Debian 14 1.15.2-1
