Which packages are affected by CVE-2026-28466?

CVE-2026-28466 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-28466?

Update openclaw to 2026.2.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-28466 is resolved across your whole dependency graph.

How do I detect CVE-2026-28466 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-2026-28466 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-2026-28466 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2026-28466, including . All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2026-28466?

CVE-2026-28466 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th 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-2026-28466?

CVE-2026-28466 is classified as CWE-863 (CWE-863). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-28466 published, and has it been updated?

CVE-2026-28466 was published on March 5, 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

Summary

A remote code execution (RCE) vulnerability in the gateway-to-node invocation path allowed an authenticated gateway client to bypass node-host exec approvals by injecting internal control fields into node.invoke parameters.

Affected Component

Gateway method: node.invoke for node command system.run
Node host runner: exec approval gating for system.run

Impact

If an attacker can authenticate to a gateway (for example via a leaked/shared gateway token or a paired device token with operator.write), they could execute arbitrary commands on connected node hosts that support system.run. This can lead to full compromise of developer workstations, CI runners, and servers running the node host.

Technical Details

The gateway forwarded user-controlled params to node hosts without sanitizing internal approval fields. The node host treated params.approved === true and/or params.approvalDecision as sufficient to skip the approval workflow.

Fix

Patched in OpenClaw 2026.2.14.

Gateway strips untrusted approval control fields from system.run user input.
Gateway only re-attaches approval flags when params.runId references a valid exec.approval.request record and the request context matches. Approval IDs are bound to the requesting device identity (stable across reconnects), preventing replay by other clients.
Gateway forwards only an allowlisted set of system.run parameters, preventing future control-field smuggling.

Mitigations

Upgrade to 2026.2.14 or later.
Restrict access to the gateway (do not expose it to untrusted networks/users).
Rotate gateway credentials if you suspect token/password exposure.
Disable remote command execution on nodes by blocking system.run at the gateway (gateway.nodes.denyCommands) and/or by configuring node exec security to deny.
