Prototype pollution in axios - CVE-2026-44495
Published: May 29, 2026
Vulnerability details
The vulnerability allows a remote attacker to execute injected code in the Axios request-processing context, disclose sensitive information, tamper with response data, or cause a denial of service.
The vulnerability exists due to improperly controlled modification of object prototype attributes in Axios request config processing and response transformation when handling requests after Object.prototype has been polluted with a crafted transformResponse value. A remote attacker can pollute Object.prototype.transformResponse through a separate prototype-pollution primitive to execute injected code in the Axios request-processing context, disclose sensitive information, tamper with response data, or cause a denial of service.
Exploitation requires a separate vulnerability or equivalent capability to control Object.prototype in the same JavaScript process or browser context before Axios merges or validates the request config. Browser and Node usage can both be affected.
