Description
Five config properties in the HTTP adapter are read via direct property access without hasOwnProperty guards, making them exploitable as prototype pollution gadgets. When Object.prototype is polluted by another dependency in the same process, axios silently picks up these polluted values on every outbound HTTP request.
Recommendation
Update the axios package to the latest compatible version. Followings are version details:
- Affected version(s): >= 1.0.0, < 1.15.2
- Patched version(s): 1.15.2
