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.
