CVE-2026-101880
CVE-2026-101880 — OpenClaw Windows Node before 2026.7.1 Authorization Bypass
OpenClaw Windows Node before 2026.7.1 contains an incorrect authorization vulnerability in the system.run exec-approval policy where ExecShellWrapperParser fails to split commands on pipe operators or extract command substitutions. Connected gateways or agents can bypass approval rules by placing denied commands behind allowed prefixes using pipe operators or command substitution syntax, achieving arbitrary command execution on Windows hosts.

Remediation
The vendor's own words where we have them.
Upgrade OpenClaw Windows Node to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.
First 24 hours
Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.
- Identify exposed assets running affected vendor/product/version combinations.
- Prioritize based on EPSS, PoC availability, and external exposure.
- Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

Answered from this record1
What should defenders know first?
CVE-2026-101880 is OpenClaw Windows Node before 2026.7.1 Authorization Bypass, a high vulnerability affecting OpenClaw Windows Node from OpenClaw. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-101880. Public exploit evidence is: 1 public PoC repositories reported; 0 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 8.8 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
