CVE-2026-42041— Axios 授权问题漏洞

Axios: Authentication Bypass via Prototype Pollution Gadget in `validateStatus` Merge Strategy

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution to silently suppress all HTTP error responses (401, 403, 500, etc.), causing them to be treated as successful responses. This completely bypasses application-level authentication and error handling. The root cause is that validateStatus is the only config property using the mergeDirectKeys merge strategy, which uses JavaScript's in operator — an operator that inherently traverses the prototype chain. When Object.prototype.validateStatus is polluted with () => true, all HTTP status codes are accepted as success. This vulnerability is fixed in 1.15.1 and 0.31.1.

Axios 授权问题漏洞

Axios是Axios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 1.15.1之前版本和0.31.1之前版本存在授权问题漏洞，该漏洞源于validateStatus使用mergeDirectKeys合并策略，该策略使用in运算符遍历原型链，导致Object.prototype.validateStatus被污染时所有HTTP状态码被视为成功。
