Overview
openclaw is a 🦞 OpenClaw — Personal AI Assistant
Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition via a TOCTOU race condition in OpenShell local mirror filesystem mutation operations (remove, mkdir, and rename). These operations can act on a different filesystem target after the sandbox path-safety check completes, if the path is changed concurrently by another actor. An attacker who wins 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.
