Root Cause Analysis
The vulnerability stems from improper header sanitization in request handling. The patch introduced a new 'removingHopByHopHeaders' function called from 'impersonateHandler', indicating the previous lack of header sanitization was the flaw. The 'impersonateHandler' is directly responsible for setting impersonation headers and forwarding requests, making it the vulnerable entry point where header validation was missing. The connection header manipulation exploit path described in CVE-2022-23652 aligns with this code location.
