How to fix?

Upgrade Debian:unstable etcd to version 3.4.23-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream etcd package and not the etcd package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
