Published Sep 26, 2026CWE-367EPSS 0.08%

Overview

CVE-2026-100597 is a high-severity vulnerability. It was published on September 26, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

OpenClaw (npm package 'openclaw') before 2026.7.1 is vulnerable to a time-of-check time-of-use race condition in OpenShell local mirror filesystem mutation operations. The remove, mkdir, and rename operations could act on a different filesystem target after OpenClaw completed its sandbox path-safety check, if the path is changed concurrently. An attacker able to win the race can cause a sandboxed operation to delete, create, or rename a host path outside the intended mirror root with the permissions of the OpenClaw process user. This does not require an operator to have granted host filesystem access outside the sandbox. The issue is fixed in 2026.7.1.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
