How do I detect CVE-2026-41378 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-2026-41378 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-2026-41378 actively exploited in the wild?

Description

Summary

Paired node escalates to gateway RCE via unrestricted node.event agent dispatch

Current Maintainer Triage

Status: narrow
Normalized severity: high
Assessment: v2026.3.28 still lets paired role=node clients drive node.event agent.request into broader gateway-side tool access than node RPCs, but critical is overstated because a trusted paired node foothold is already required.
