CVE-2026-32064 OpenClaw CVE debrief

Who should care

Defenders and administrators responsible for OpenClaw deployments, particularly those using the sandbox browser, should assess exposure and prioritize remediation. They should verify and restrict access to the exposed noVNC port on the host loopback interface. Remediation priority is high for OpenClaw versions prior to 2026.2.21. Evidence is limited to CVE record and source item details; further verification may be necessary to assess exposure and mitigate

Why it matters

CVE-2026-32064 allows unauthenticated access to the VNC interface in OpenClaw versions prior to 2026.2.21, impacting defenders who use the sandbox browser and requiring prompt verification and remediation.
