The sandbox browser entrypoint launched
x11vnc without authentication (-nopw) for noVNC observer sessions.OpenClaw-managed runtime flow publishes the noVNC port to host loopback only (
127.0.0.1), so default exposure is local to the host unless operators explicitly expose the port more broadly (or run the image standalone with broad port publishing).Affected Packages / Versions
- Package:
docker/openclaw - Affected:
<= 2026.2.19-2 - Patched:
>= 2026.2.21
Technical details
scripts/sandbox-browser-entrypoint.shusedx11vnc ... -nopwfor noVNC observer flow.websockifyexposed noVNC for the container listener.- OpenClaw runtime (
src/agents/sandbox/browser.ts) already mapped host publish to loopback, but observer auth was missing.
Fix
- Require VNC password auth in the sandbox browser entrypoint (
x11vnc -rfbauth), replacing-nopw. - Generate per-container noVNC password in runtime and inject
OPENCLAW BROWSER NOVNC PASSWORD. - Emit short-lived noVNC observer token URLs instead of sharing raw noVNC passwords in shared URLs.
- Keep loopback-only host port publish and bump sandbox browser security hash epoch.
- Add security audit findings for sandbox browser containers that publish ports on non-loopback interfaces.
Operational note: rebuild the sandbox browser image and recreate browser containers so existing containers pick up the fix.
