A fix is available — apply it.

ClawHub (openclaw/clawhub) contains an incorrect authorization vulnerability in the ClawHub application/backend: an organization-owned skill retains the ownerUserId of its original publisher, and transfer and lifecycle authorization checks trust that historical user before requiring current organization privileges. An authenticated user who originally published an organization skill can therefore transfer, delete, or restore that skill — taking control of its trusted name and history — even after their organization privileges have been revoked or downgraded. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41; the complete historical affected range was not established. It is fixed by PR #3680, included in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650, which was deployed to clawhub.ai on 2026-09-11; self-hosted deployments should update to that revision or a later descendant. The npm CLI and OpenClaw runtime are separate products and are not affected.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
