Bundler sometimes chooses a dependency source based on the highest gem
version number, which means that a rogue gem found at a public source
may be chosen, even if the intended choice was a private gem that is a
dependency of another private gem that is explicitly depended on by the
application. (CVE-2020-36327)

The REXML gem does not properly address XML round-trip issues. An
incorrect document can be produced after parsing and serializing.

In RDoc it is possible to execute arbitrary code via | and tags in a
filename. (CVE-2021-31799)

A malicious FTP server can use the PASV response to trick Net::FTP into
connecting back to a given IP address and port. This potentially makes
curl extract information about services that are otherwise private and not
disclosed (e.g., the attacker can conduct port scans and service banner
extractions).  (CVE-2021-31810)

Ruby Net::IMAP does not raise an exception when StartTLS fails with an an
unknown response, which might allow man-in-the-middle attackers to bypass
the TLS protections by leveraging a network position between the client
and the registry to block the StartTLS command, aka a "StartTLS stripping
attack." (CVE-2021-32066)

Buffer Overrun in CGI.escape_html (CVE-2021-41816)
