Summary
OpenClaw: Browser SSRF policy default allowed private-network navigation
Details

Summary

Browser SSRF policy default allowed private-network navigation.

Affected Packages / Versions

  • Package: openclaw
  • Ecosystem: npm
  • Affected versions: < 2026.4.14
  • Patched versions: >= 2026.4.14

Impact

Browser SSRF protection could allow private-network navigation by default in paths where restrictive behavior was expected, exposing internal services or metadata endpoints through browser-driven requests.

Technical Details

The fix preserves strict SSRF configuration semantics, keeps private-network access disabled unless explicitly opted in, and updates loopback CDP readiness handling for the stricter default.

Fix

The issue was fixed in #66354 and #66386. The first stable tag containing the fix is v2026.4.14, and openclaw@2026.4.14 includes the fix.
