Kerentanan Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling'). Skor CVSS 3.0 6.5 (Medium) menurut hackerone.com.

Deskripsi (NVD)

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.
