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 - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## 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.
