CVE-2026-44494 is a prototype pollution gadget in Axios's Node.js HTTP adapter affecting versions 1.0.0 through versions before 1.16.0. The adapter reads config.proxy using ordinary JavaScript property lookup, which traverses the prototype chain. Because Axios defaults do not define proxy, the merged configuration can lack an own proxy property and inherit an attacker-controlled Object.prototype.proxy value. The setProxy() function then redirects outbound requests through the attacker-controlled proxy, enabling traffic interception and modification. Axios does not itself create the prerequisite prototype pollution; exploitation requires a separate pollution source in the same JavaScript runtime. Browser environments using the XHR adapter are not affected by this code path. The legacy 0.x branch is also tracked as affected before 0.32.0.
