"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-150110 advisory.

    Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as 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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
