NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:16/nodejs-nodemon package and not the nodejs:16/nodejs-nodemon package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

Undici is an HTTP/1.1 client for Node.js. Prior to version 5.19.1, the Headers.set() and Headers.append() methods are vulnerable to Regular Expression Denial of Service (ReDoS) attacks when untrusted values are passed into the functions. This is due to the inefficient regular expression used to normalize the values in the headerValueNormalize() utility function. This vulnerability was patched in v5.19.1. No known workarounds are available.
