OpenClaw: Forwarding header spoofing bypasses gateway.trustedProxies origin detection
Summary
When gateway.trustedProxies was configured, spoofed loopback hops in forwarding headers could be accepted as the client origin and weaken downstream auth and rate-limit decisions.
Affected Packages / Versions

openclaw(npm) - Affected: < 2026.3.22
- Fixed: >= 2026.3.22

Fix Commit(s)
fc2d29ea926f47c428c556e92ec981441228d2a4
Release Status
The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.
Code-Level Confirmation
- src/gateway/net.ts now ignores loopback forwarded hops before trusted-proxy client resolution.
- That shipped origin fix is the one consumed by canvas auth and gateway auth-rate-limit paths that rely on resolved client identity.
OpenClaw thanks @lintsinghua for reporting.
