CVE-2026-100597: OpenClaw before 2026.7.1 Path Traversal via Filesystem Race

Severity: high (CVSS 7.8 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.1% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-09-26 · updated 2026-09-30
Weakness: CWE-367

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.
