axios Vulnerable to Credential Theft and Response Hijacking via Prototype Pollution Gadget in Config Merge

Description

Axios versions before the fixed releases 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.

Recommendation

Update the axios package to the latest compatible version. Followings are version details:

• Affected version(s): **>= 0.19.0, < 0.31.1

  >= 1.0.0, < 1.15.2**

• Patched version(s): **0.31.1

  1.15.2**
