# bug-1948: apiserver trusts X-Forwarded-For from any client, so IP whitelist and JWT IP binding can be spoofed
|
|
|
|
## Description
|
|
**Observed:** (source reading, `.kiro/reviews/project-gap-review-2026-10-10.md` (P0); to be confirmed by a failing test before the fix)
|
|
The router uses `gin.Default()` (`router/routers.go:19`) and never calls `SetTrustedProxies`, so `ClientIP()` honours `X-Forwarded-For` from any peer.
|
|
|
|
**Expected:** Forwarded headers are only honoured from configured trusted proxies.
|
|
**Impact:** Security: a client can claim any IP and bypass the IP whitelist and the IP bound into its JWT.
|
|
**Found by:** review: `.kiro/reviews/project-gap-review-2026-10-10.md` (P0)
|
|
## Environment
|
|
- OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
|
|
- libc: glibc 2.42-47 (interpreter /nix/store/wb6rhpznjfczwlwx23zmdrrw74bayxw4-glibc-2.42-47/lib/ld-linux-x86-64.so.2)
|
|
- Toolchain: gcc (GCC) 15.2.0, meson 1.9.1
|
|
- Build: asan (xce.build)
|
|
- Code: scheduler-framework @ 94472ee3-dirty
|
|
- Deployment: any (found by source reading; the failing test that confirms it is named in Verification)
|
|
|
|
## Reproduction
|
|
1. Send a request with `X-Forwarded-For: <whitelisted IP>` from a non-whitelisted host.
|
|
2. It passes the whitelist.
|
|
- Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
|
|
- Evidence: the code sites quoted in Description; no logs kept.
