Description
A flaw was found in Axios, a promise-based HTTP client. This vulnerability, known as prototype pollution, allows an upstream dependency to modify the fundamental behavior of JavaScript objects. When this occurs, Axios can unknowingly incorporate these altered values, leading to two potential consequences. This can result in sensitive information being inadvertently included in network requests, or cause application instability and crashes, leading to a denial of service.

Exploitation could lead to sensitive information disclosure in network requests or result in application instability and denial of service, particularly in environments where Object.prototype is modified by other components.
