DescriptionNVD

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.

AnalysisAI

Axios HTTP client prior to version 1.15.1 (1.x branch) and 0.31.1 (0.x branch) fails to enforce maxContentLength limits when responseType is set to 'stream', allowing attackers to cause denial of service by streaming unbounded response payloads that bypass configured size restrictions. The vulnerability affects both browser and Node.js environments and requires no authentication or user interaction to exploit.
