CVE-2026-42264 Details
Description
Axios is a promise based HTTP client for the browser and Node.js. From version 1.0.0 to before version 1.15.2, fFive config properties (auth, baseURL, socketPath, beforeRedirect, and insecureHTTPParser) in the HTTP adapter are read via direct property access without hasOwnProperty guards, making them exploitable as prototype pollution gadgets. When Object.prototype is polluted by another dependency in the same process, axios silently picks up these polluted values on every outbound HTTP request. This issue has been patched in version 1.15.2.
A prototype pollution vulnerability has been identified in Axios versions 1.0.0 prior to 1.15.2. This issue arises in the HTTP adapter, where five configuration properties are accessed directly without proper safeguards. When 'Object.prototype' is polluted by another dependency, Axios can unintentionally incorporate these contaminated values into outgoing HTTP requests. The vulnerable properties include 'auth', 'baseURL', 'socketPath', 'beforeRedirect', and 'insecureHTTPParser'. This vulnerability can lead to unauthorized credential injection, request redirection to malicious servers, exploitation of internal Unix sockets, execution of arbitrary functions during HTTP redirects, and a weakened HTTP parser that could facilitate request smuggling.
Users can upgrade to Axios version 1.15.2 or later, where this vulnerability has been patched.
