Upgrade node
to version 15.10.0, 14.16.0, 12.21.0, 10.24.0 or higher.
Overview
node is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Affected versions of this package are vulnerable to DNS Rebinding. A Denial of Service can occur when the whitelist in /etc/hosts
includes localhost6
. If an attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the localhost6
domain.
