A fix is available — apply it.

OpenClaw Windows Node before 2026.7.1 contains an incomplete validation vulnerability in system.execApprovals.set that accepts wildcard-executable rules and abusable system binaries like mshta, rundll32, and certutil. Remote callers can add broad allow rules to execute arbitrary commands on the Windows host through system.run without operator checks or user prompts.

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

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). 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.
