CVE-2026-44495

Axios: Credential Theft and Response Hijacking via Prototype Pollution Gadget in Config Merge PUBLISHED

Description (CNA)

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.

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.
