Summary
Axios versions from 0.19.0 to before 0.31.1 and 1.15.2 contain prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator.
Risk Assessment
The risk is that an attacker, by exploiting another vulnerability to pollute the prototype, could influence Axios behavior, potentially modifying HTTP request handling or bypassing option validation, leading to unauthorized actions.
Recommendation
It is recommended to immediately upgrade Axios to version 0.31.1 or 1.15.2, which contain the fix for this vulnerability.
Original NVD description (English source)
Axios is a promise based HTTP client for the browser and Node.js. From 0.19.0 to before 0.31.1 and 1.15.2, Axios contains prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator. Axios does not itself create the prototype pollution. Exploitability requires a separate prototype-pollution vulnerability or equivalent attacker control over Object.prototype before Axios creates a request. This vulnerability is fixed in 0.31.1 and 1.15.2.
