Quick assessment

Affected
axios axios
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Axios是Axios团队开源的一款基于Promise(异步编程的一种解决方案)的HTTP客户端。 Axios 1.7.0版本至1.18.0之前版本存在资源管理错误漏洞，该漏洞源于在无法确定Content-Length时，fetch适配器未能对WHATWG ReadableStream请求主体强制实施maxBodyLength限制，可能导致攻击者提供未知长度的流数据绕过上传大小限制，造成不受控制的网络出口或资源耗尽。

Vulnerability Title
axios 1.7.0 before 1.18.0 maxBodyLength Bypass via ReadableStream
Source: CVE Program / CVE List V5
Vulnerability 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.
