CVE-2018-1098: Cross-Site Request Forgery (CSRF)
(updated )
A cross-site request forgery flaw was found in etcd 3.3.1 and earlier. 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.
