AI-suggested
Upgrade Axios to version 1.15.1 or later, or 0.31.1 or later, where this vulnerability is fixed. Since the vulnerability depends on prototype pollution in the application's dependency tree, ensure that all dependencies are also free from prototype pollution issues. No other mitigations are indicated.
Description
Axios versions prior to 1.15.1 and 0.31.1 contain a prototype pollution vulnerability in the HTTP adapter that allows attackers to inject arbitrary HTTP headers into outgoing requests. This occurs because Axios misidentifies plain object payloads as FormData instances when Object.prototype is polluted with certain functions, leading to execution of attacker-controlled header injection. The vulnerability is fixed in versions 1.15.1 and 0.31.1.
