Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Two separate fixes address authentication bypass in the proxy, one for missing auth headers on upgraded requests and another for incorrect upgrade detection. These indicate the upgrade path is a fragile area where auth context can be lost or misapplied.
SSRF: The proxy allows redirects, and without same-host enforcement, an attacker could trick the server into making requests to internal endpoints. The fix enforces requireSameHostRedirects in the SPDY round tripper.
Denial of Service: Three separate dependency bumps were needed to fix panic vulnerabilities in json-patch, indicating a recurring pattern of DoS via malformed JSON patches. This dependency is widely used and must be kept patched.
