CVE-2026-32029 — OpenClaw < 2026.2.21 - Client IP Spoofing via X-Forwarded-For Header Parsing

Affected: OpenClaw

OpenClaw versions prior to 2026.2.21 improperly parse the left-most X-Forwarded-For header value when requests originate from configured trusted proxies, allowing attackers to spoof client IP addresses. In proxy chains that append or preserve header values, attackers can inject malicious header content to influence security decisions including authentication rate-limiting and IP-based access controls.

GHSA-2rgf-hm63-5qph — OpenClaw improperly parses X-Forwarded-For behind trusted proxies allows client IP spoofing in security decisions

Affected: npm: openclaw

### 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.
