CVE-2026-43527 — OpenClaw < 2026.4.14 - Server-Side Request Forgery via Private Network Navigation

Affected: OpenClaw

OpenClaw before 2026.4.14 contains a server-side request forgery vulnerability in browser SSRF policy that allows private-network navigation by default. Attackers can exploit this misconfiguration to access internal services or metadata endpoints through browser-driven requests.

GHSA-53vx-pmqw-863c — OpenClaw: Browser SSRF policy default allowed private-network navigation

Affected: npm: openclaw

## 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.

## Release Process Note

Users should upgrade to `openclaw` 2026.4.14 or newer. The latest npm release, `2026.4.14`, already includes the fix.
