Updates are now available for the v18.x, v20.x and 21.x Node.js release lines for the following issues.
This security release includes the following dependency updates to address public vulnerabilities:
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.
Impacts:
Thank you, to bart for reporting this vulnerability and Anna Henningsen for fixing it.
The team has identified a 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.
Impacts:
Thank you, to bpingel for reporting this vulnerability and Paolo Insogna for fixing it.

The 18.x release line of Node.js is vulnerable to 1 medium severity issue, 1 high severity issue. The 20.x release line of Node.js is vulnerable to 1 medium severity issue, 1 high severity issue. The 21.x release line of Node.js is vulnerable to 1 medium severity issue, 1 high severity issue.
