A fix is available — apply it.

OpenClaw (npm package 'openclaw') before 2026.7.1 does not enforce the administrator scope requirement on browser control when it is reached through the node.invoke method, although direct browser.request access requires administrator scope. In Gateway deployments that honor caller identity and narrower operator scopes, a write-scoped caller with access to a connected browser-capable node can inspect pages, navigate tabs, or interact with browser-visible applications without the configured admin requirement; practical impact depends on the browser profile and signed-in state. Shared-secret token and password callers are considered fully trusted operators under OpenClaw's security model and are not affected. The issue is fixed in 2026.7.1.

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.
