OpenClaw has incomplete IPv4 special-use SSRF blocking in web fetch guard

  • Disclosed: 04.03.2026
  • Updated: 11.10.2026 10:22

Summary

isPrivateIpv4() in bundled SSRF guard code missed several IPv4 special-use/non-global ranges, so web_fetch could allow targets that should be blocked by SSRF policy.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published affected version: 2026.2.21-2 (published 2026-02-21)
  • Structured vulnerable range: <= 2026.2.21-2
  • Planned patched version (pre-set): >= 2026.2.22

Impact

Low severity. Exploitation requires network reachability to the relevant special-use ranges and a request path that reaches web_fetch URL fetching.

Technical Details

Affected releases used narrow IPv4 private-range checks that omitted multiple RFC special-use/non-global ranges. This allowed requests such as http://198.18.0.1/... through SSRF validation in affected releases. Follow-up hardening consolidates local-host/tailnet range checks so gateway/browser/tailnet paths share one canonical IP classification flow.
