Description
Summary
openclaw could start the sandbox browser bridge server without authentication.
When the sandboxed browser is enabled, openclaw runs a local (loopback) HTTP bridge that exposes browser control endpoints (for example /profiles, /tabs, /tabs/open, /agent/*). Due to missing auth wiring in the sandbox initialization path, that bridge server accepted requests without requiring gateway auth.
Impact
A local attacker (any process on the same machine) could access the bridge server port and:
- enumerate open tabs and retrieve CDP WebSocket URLs
- open/close/navigate tabs
- execute JavaScript in page contexts via CDP
- exfiltrate cookies/session data and page contents from authenticated sessions
This is a localhost-only exposure (CVSS AV:L), but provides full browser-session compromise for sandboxed browser usage.
Affected Versions
- Introduced in:
2026.1.29-beta.1 (first npm release that shipped the sandbox browser bridge)
- Affected range:
>=2026.1.29-beta.1 <2026.2.14
Patched Versions
Mitigation
- Upgrade to
2026.2.14 (recommended).
- Or disable the sandboxed browser (
agents.defaults.sandbox.browser.enabled=false).
Fix Details
- The sandbox browser bridge server now always requires auth and enforces the same gateway browser control auth (token/password) that loopback browser clients already use.
- Additional hardening: bridge server refuses non-loopback binds; local helper servers are bound to loopback.
- Added regression tests (including unit coverage for per-port bridge auth fallback).
Fix commits:

NVD description
OpenClaw versions 2026.1.29-beta.1 prior to 2026.2.14 contain a vulnerability in the sandbox browser bridge server in which it accepts requests without requiring gateway authentication, allowing local attackers to access browser control endpoints. A local attacker can enumerate tabs, retrieve WebSocket URLs, execute JavaScript, and exfiltrate cookies and session data from authenticated browser contexts.
