CVE-2022-31150: Node.js Undici

Medium severity, CVSS 6.5. EPSS: 1.5% chance of exploitation in the next 30 days.

undici is an HTTP/1.1 client, written from scratch for Node.js. It is possible to inject CRLF sequences into request headers in undici in versions less than 5.7.1. A fix was released in version 5.8.0. Sanitizing all HTTP headers from untrusted sources to eliminate `\r\n` is a workaround for this issue.

Affected products

• Node.js Undici: before 5.8.0 (fixed in 5.8.0)
