Affected packages
• npm openclaw: < 2026.4.14 → fixed in 2026.4.14
Description
Summary
Browser SSRF policy default allowed private-network navigation.
Affected Packages / Versions
• Package: `openclaw`
• Ecosystem: npm
• Affected 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 `[email protected]` includes the fix.

• PR: #66354, #66386
Release Process Note
