What's new in this version:

Improper handling of URI Subject Alternative Names (Medium)(CVE-2021-44531):
- 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. This behavior can be reverted through the --security-revert command-line option

Certificate Verification Bypass via String Injection (Medium)(CVE-2021-44532):
- Node.js converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.
- Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.

Incorrect handling of certificate subject and issuer fields (Medium)(CVE-2021-44533):
- Node.js did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.
- Affected versions of Node.js do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable.

Prototype pollution via console.table properties (Low)(CVE-2022-21824):
- Due to the formatting logic of the console.table() function it was not safe to allow user controlled input to be passed to the properties parameter while simultaneously passing a plain object with at least one property as the first parameter, which could be __proto__. The prototype pollution has very limited control, in that it only allows an empty string to be assigned numerical keys of the object prototype.
- Versions of Node.js with the fix for this use a null protoype for the object these properties are being assigned to
