OpenClaw improperly parses X-Forwarded-For behind trusted proxies allows client IP spoofing in security decisions
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.

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.
