Path Traversal
This npm package has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted.

Improper Certificate Validation
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 does 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.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The npm package "tar" (aka node-tar) has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat calls to determine whether a given path is a directory, paths are cached when directories are created.

Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
The llhttp parser accepts requests with a space (SP) right after the header name before the colon. This can lead to HTTP Request Smuggling (HRS).

json-schema is vulnerable to Prototype Pollution
json-schema before version 0.4.0 is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution').

Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
This advisory has been marked as a false positive.

Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
The parse function in llhttp ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions.
