Overview

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). An attacker can set up a website that tries to send a POST request to the etcd server and modify a key. Adding a key is done with PUT so it is theoretically safe (can't PUT from an HTML form or such) but POST allows creating in-order keys that an attacker can send.
