Description

axios versions 1.7.0 before 1.18.0 fail to enforce maxBodyLength for WHATWG ReadableStream request bodies in the fetch adapter when Content-Length cannot be determined. Attackers can supply unknown-length stream data to bypass upload size limits and cause uncontrolled network egress or resource exhaustion.

Affected products

How to fix

Upgrade to a fixed version: axios 1.18.0. Check the vendor advisory for mitigations.
