Doc Text:
A flaw was found in node.js where it accepted a certificate's Subject Alternative Names (SAN) entry, as opposed to what is specified by the HTTPS protocol. This flaw allows an active person-in-the-middle to forge a certificate and impersonate a trusted host.

Description Guilherme de Almeida Suckevicz 2022-01-14 19:28:17 UTC 
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 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.
