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

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.
