CVE-2021-22884 log

Severity Medium
Remote Yes
Type Denial of service
Node.js before versions 15.10.0, 14.16.0, 12.21.0 and 10.24.0 is vulnerable to denial of service attacks when the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160.
