Node.js is an open-source, cross-platform, JavaScript runtime environment, it executes JavaScript code outside of a browser.
Security Fix(es):
The team has identified a critical vulnerability in the http server of the most recent version of Node, where malformed headers can lead to HTTP request smuggling. Specifically, if a space is placed before a content-length header, it is not interpreted correctly, enabling attackers to smuggle in a second request within the body of the first.(CVE-2024-27982)
An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.(CVE-2024-27983)
Undici is an HTTP/1.1 client, written from scratch for Node.js. Undici cleared Authorization and Proxy-Authorization headers for fetch(), but did not clear them for undici.request(). This vulnerability was patched in version(s) 5.28.4 and 6.11.1.
(CVE-2024-30260)
Undici is an HTTP/1.1 client, written from scratch for Node.js. An attacker can alter the integrity option passed to fetch(), allowing fetch() to accept requests as valid even if they have been tampered. This vulnerability was patched in version(s) 5.28.4 and 6.11.1.(CVE-2024-30261)
