CVE: CVE-2020-8265,

Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a
use-after-free bug in its TLS implementation. When writing to a TLS enabled
socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly
allocated WriteWrap object as first argument. If the DoWrite method does not
return an error, this object is passed back to the caller as part of a
StreamWriteResult structure. This may be exploited to corrupt memory leading
to a Denial of Service or potentially other exploits. (CVE-2020-8265).

Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of
a header field in an HTTP request (for example, two Transfer-Encoding header
fields). In this case, Node.js identifies the first header field and ignores
the second. This can lead to HTTP Request Smuggling. (CVE-2020-8287).
