No CVSS score has been assigned to CVE-2026-32064 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-32064?

CVE-2026-32064 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-32064?

Update openclaw to 2026.2.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32064 is resolved across your whole dependency graph.

How do I detect CVE-2026-32064 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-32064 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2026-32064 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-32064 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-32064?

CVE-2026-32064 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 45th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-32064?

CVE-2026-32064 is classified as Missing Authentication (CWE-306). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-32064 published, and has it been updated?

CVE-2026-32064 was published on March 21, 2026 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

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.sh used x11vnc ... -nopw for noVNC observer flow.
websockify exposed 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.
