Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is
specifically defined to use a particular SAN type, can result in bypassing
name-constrained intermediates. Node.js < 12.22.9, < 14.18.3, < 16.13.2,
and < 17.3.1 was accepting URI SAN types, which PKIs are often not defined
to use. Additionally, when a protocol allows URI SANs, Node.js did not
match the URI correctly.Versions of Node.js with the fix for this disable
the URI SAN type when checking a certificate against a hostname. This
behavior can be reverted through the --security-revert command-line option.
