What is CVE-2026-32064?

An issue exists in OpenClaw versions before 2026.2.21, where the sandbox browser's noVNC observer sessions are launched without authentication for the x11vnc service. This flaw allows remote attackers with access to the host loopback interface to connect to the exposed noVNC port. Consequently, they can observe or interact with the sandbox browser without needing any credentials, potentially leading to unauthorized access or data exposure.
