Summary

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when responseType: 'stream' is used, Axios returns the response stream without enforcing maxContentLength. This bypasses configured response-size limits and allows unbounded downstream consumption. 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
