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.
openclaw (npm)2026.2.21-2 (published 2026-02-21)<= 2026.2.21-2>= 2026.2.22Low severity. Exploitation requires network reachability to the relevant special-use ranges and a request path that reaches web_fetch URL fetching.
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.
