Summary

OpenShell FS bridge writes stay pinned to the sandbox mount root

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.4.21
Fixed version: 2026.4.22

Impact

A time-of-check/time-of-use race around OpenShell sandbox filesystem writes could let a symlink swap redirect a write outside the intended local mount root.

Fix

OpenShell write paths now validate the canonical target against the mount root, reject unsafe symlink parents and symlink leaves for writes, and use root-scoped write helpers before syncing to the remote sandbox.
