CVE-2026-67318 Details
Description
axios versions >=1.13.0 (Node.js HTTP adapter) fail to enforce the configured maxBodyLength limit on streamed request bodies when requests are sent with httpVersion: 2. Because Node's HTTP/2 request API does not honor the maxBodyLength option and axios's byte-counting stream wrapper is gated on maxRedirects === 0, an attacker who controls a stream passed to axios can cause the application to transmit outbound data exceeding the configured finite maxBodyLength. Impact is limited to resource consumption and policy bypass (excess egress, upstream quota consumption, limited availability); it does not enable code execution, credential disclosure, or request-destination control. Calls using the default maxBodyLength: -1 and browser adapters are not affected.
A vulnerability exists in Axios versions 1.13.0 prior to 1.18.0 when the Node.js HTTP adapter is used. The issue arises because these Axios versions do not properly enforce the maxBodyLength limit on streamed request bodies sent over HTTP/2. This oversight allows an attacker to manipulate a stream passed to Axios, causing the application to send more data than intended, thereby bypassing established egress policies and consuming additional upstream resources. While this vulnerability can lead to increased resource usage and potential availability issues, it does not allow for code execution, credential disclosure, or control over the request destination.
Users can upgrade to Axios version 1.18.0 or later, where this vulnerability has been addressed. For those using Axios versions 1.15.1 or later, setting maxRedirects to 0 on affected HTTP/2 streamed upload calls can mitigate the issue.
