Description
A flaw was found in Axios, a promise-based HTTP client. This vulnerability involves prototype pollution gadgets in the request configuration processing. If another vulnerability has already polluted the Object.prototype.transformResponse, affected Axios versions may incorrectly interpret this inherited value as part of the 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.
Statement
This Important vulnerability in Axios, a promise-based HTTP client, can lead to information disclosure, including credential theft and response hijacking, or denial of service. Exploitation requires a separate prototype pollution vulnerability in the same JavaScript process, allowing an attacker to control Object.prototype.transformResponse. Red Hat products using affected Axios versions are at risk if another component introduces such pollution.
