### Summary

OpenClaw used left-most `X-Forwarded-For` values when requests came from configured trusted proxies. In proxy chains that append/preserve header values, this could let attacker-controlled header content influence security decisions tied to client IP.

### Affected Packages / Versions

- Package: `openclaw` (npm) - Affected: `<= 2026.2.19-2` - Patched: `2026.2.21` (planned next release)

### Impact

Possible client-IP spoofing in security-sensitive paths (for example auth rate-limit identity and local/private classification) for deployments behind trusted proxies with non-recommended forwarding behavior.

### Scope Note

OpenClaw docs recommend reverse proxies overwrite (not append/preserve) inbound forwarding headers. This condition reduces severity.

### Fix Commit(s)

- `07039dc089e51589a213ec0d16f8d6f2cd871fa1` - `8877bfd11ec7760b115b2d0d7500a45da2749747`

### Release Process Note

`patched_versions` is pre-set to the planned next release (`2026.2.21`). After npm release is out, publish this advisory.

OpenClaw thanks @AnthonyDiSanti for reporting.
