fix: allow header-based routing when Host is an IP address by tomassrnka · Pull Request #2581 · e2b-dev/infra

tomassrnka · 2026-05-06T14:37:08Z

Summary

Fixes a regression from #2540 that broke SDK connectivity for any IP-based access to the client-proxy (bridge networks, LAN, on-prem deployments, e2b-local).

isLocalRequestHost() only accepted localhost and loopback IPs (127.0.0.1, ::1)
When the SDK connects via an IP like 192.168.100.66:3002, routing headers (E2b-Sandbox-Id, E2b-Sandbox-Port) were silently ignored
parseHost() then tried to extract a sandbox ID from the IP address and failed with ErrInvalidHost → HTTP 400

The fix: widen isLocalRequestHost() from ip.IsLoopback() to ip != nil.

This is safe because the shouldParseHeaders guard exists to prevent header spoofing on per-sandbox hostnames like 49983-sbx.e2b.app, where the hostname is authoritative. An IP address can never contain sandbox routing info — parseHost() will always fail on it — so there is nothing for headers to conflict with. Headers are the only routing mechanism that can work for IP hosts.

The per-sandbox hostname guard is unaffected: headers are still ignored when r.Host is a domain like 49983-sbx.e2b.app.

How it was found

e2b-local nightly build on 2026-05-05 failed the sandbox smoke test. The build itself succeeded, but sandbox.commands.run() returned HTTP 400 because the client-proxy rejected the bridge network host 192.168.100.66:3002:

WARN  invalid host  {"host": "192.168.100.66:3002"}  handler.go:30

The previous night's build (using commit 92ea305dd, before #2540) passed. Today's build (using ae68b805a, after #2540) failed.

Test plan

All existing TestGetTargetFromRequest tests pass
Added test cases for private IPv4, 10.x network, and public IPv4 hosts
Verify e2b-local nightly build passes with this fix

🤖 Generated with Claude Code

#2540 introduced shouldParseHeaders() to guard against header spoofing on per-sandbox hostnames (e.g. 49983-sbx.e2b.app), where the sandbox ID is encoded in the hostname and headers should not override it. However, isLocalRequestHost() only accepted localhost and loopback IPs, which means any IP-based access (bridge networks, LAN, on-prem) was rejected — the proxy ignored routing headers and fell through to parseHost(), which cannot extract a sandbox ID from an IP address. An IP address can never contain sandbox routing info in its hostname, so there is nothing for headers to conflict with. parseHost() will always fail on an IP host regardless. Headers are the only routing mechanism that can work. Widen the check from ip.IsLoopback() to ip != nil so header-based routing works for all IP hosts. The per-sandbox hostname guard is unaffected — headers are still ignored for hosts like 49983-sbx.e2b.app where the hostname is authoritative. Discovered via e2b-local nightly build failure: the SDK connects to the client-proxy via a bridge network IP (192.168.100.66:3002) and was getting HTTP 400 "invalid host" on every sandbox command.

PR Summary

Medium Risk
Expands the set of requests eligible for header-based routing to any IP host, which could enable header spoofing if the proxy is reachable via raw IP from untrusted networks. Behavior is otherwise narrowly scoped and covered by added tests.

Overview
Updates isLocalRequestHost() so header-based sandbox routing (E2b-Sandbox-Id/E2b-Sandbox-Port) is allowed whenever Host parses as an IP address (not just loopback), preventing IP-host requests from falling back to parseHost() and returning ErrInvalidHost. Extends TestGetTargetFromRequest with new cases covering private and public IPv4 hosts to ensure routing headers are honored for IP-based access.
