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 1.13.0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Node.js HTTP adapter在HTTP/2请求中未能强制maxBodyLength限制，可能导致资源消耗和政策绕过。

Vulnerability Title
axios 1.13.0 before 1.18.0 maxBodyLength Bypass via HTTP/2
Source: CVE Program / CVE List V5
Vulnerability 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.
