Description

A flaw was found in Axios. When 'responseType: 'stream'' is used, Axios returns the response stream without enforcing the 'maxContentLength' limit. This allows a remote attacker to bypass configured response-size limits, leading to unbounded downstream consumption of resources. This vulnerability can result in a Denial of Service (DoS) due to excessive resource usage.
