Affected packages
• npm openclaw: < 2026.2.22 → fixed in 2026.2.22
Description
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: `= 2026.2.22`
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.
