How to: CVE-2025-23167 (2025-05-19)
```
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`.\nThis inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests.\n\nThe issue was resolved by upgrading `llhttp` to version 9, which enforces correct header termination.\n\nImpact:\n* This vulnerability affects only Node.js 20.x users prior to the `llhttp` v9 upgrade.
