Summary

Duplicate Advisory: OpenClaw's andbox browser noVNC observer lacked VNC authentication

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-25gx-x37c-7pph. This link is maintained to preserve external references.

Original Description

OpenClaw versions prior to 2026.2.21 sandbox browser entrypoint launches x11vnc without authentication for noVNC observer sessions, allowing unauthenticated access to the VNC interface. Remote attackers on the host loopback interface can connect to the exposed noVNC port to observe or interact with the sandbox browser without credentials.
