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 是一个用于浏览器和 Node.js 的基于 Promise 的 HTTP 客户端。在版本 1.0.0 至 1.20.0 之间，dispatchRequest 函数在处理替换请求配置时，会规范化（normalize）继承自 Object.prototype.headers 的属性。如果存在一个同进程的原型污染漏洞导致 Object.prototype.headers 被设置，并且受信任的请求拦截器返回一个新的普通配置对象（该对象不包含自身的 headers 属性），那么在拦截器链执行完毕后，dispatc

Vulnerability Title
Axios: Header Injection via Inherited headers After Minimal Interceptor
Source: CVE Program / CVE List V5
Vulnerability Description
Axios is a promise-based HTTP client for the browser and Node.js. From 1.0.0 until 1.20.0, the dispatchRequest function normalizes inherited Object.prototype.headers from a replacement request configuration. A separate same-process prototype-pollution flaw sets Object.prototype.headers, and trusted request interceptors return a new ordinary configuration without an own headers property. After the interceptor chain, dispatchRequest resolves the inherited headers during normalization. Downstream request processing can observe attacker-controlled headers, including authorization-related values. This issue is fixed in version 1.20.0.
