NVD Description

Note: Versions mentioned in the description apply only to the upstream node-undici package and not the node-undici package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Undici is an HTTP/1.1 client for Node.js. Prior to 7.18.0 and 6.23.0, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. This vulnerability is fixed in 7.18.0 and 6.23.0.
