The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path.This misleading documentation affects all users using the experimental permission model in active release lines: 20.x and 21.x.Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js. NOTE: https://nodejs.org/en/blog/vulnerability/february-2024-security-releases/#multiple-permission-model-bypasses-due-to-improper-path-traversal-sequence-sanitization-cve-2024-21891---medium A flaw was found in Node.js. On Linux, Node.js ignores certain environment variables if they have been set by an unprivileged user while the process is running with elevated privileges, with the exception of CAP_NET_BIND_SERVICE. Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when other capabilities have been set. This may allow unprivileged users to inject code that inherits the processes elevated privileges.

The server may read an unbounded number of bytes from a single connection, which can allow an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and a denial of service. Undici is an HTTP/1.1 client, written from scratch for Node.js. Undici already cleared Authorization headers on cross-origin redirects, but did not clear `Proxy-Authentication` headers. This issue has been patched in versions 5.28.3 and 6.6.1. Users are advised to upgrade. There are no known workarounds for this vulnerability
