How to fix?

Upgrade SLES:15.4 nodejs16-docs to version 16.20.2-150400.3.42.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs16-docs package and not the nodejs16-docs package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using \r\n\rX instead of the required \r\n\r\n. This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests.

The issue was resolved by upgrading llhttp to version 9, which enforces correct header termination.

Impact:

  • This vulnerability affects only Node.js 20.x users prior to the llhttp v9 upgrade.
