Frequently Asked Questions
What is CVE-2026-100597?
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.
Is CVE-2026-100597 actively exploited?
No confirmed active exploitation of CVE-2026-100597 has been reported, but organizations should still patch proactively.

No patch is currently available. Monitor vendor advisories for updates.
What is the CVSS score for CVE-2026-100597?
CVE-2026-100597 has a CVSS v3.1 base score of 7.8 (HIGH).

Weaknesses (CWE)
CWE-367 — Time-of-check Time-of-use (TOCTOU) Race Condition: The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check.
- [Implementation] The most basic advice for TOCTOU vulnerabilities is to not perform a check before the use. This does not resolve the underlying issue of the execution of a function on a resource whose state and identity cannot be assured, but it does help to limit the false sense of security given by the check.
- [Implementation] When the file being altered is owned by the current user and group, set the effective gid and uid to that of the current user and group when executing this statement.
