Technical Details

NVD Description

## 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. ## Fix Commit(s) - 7be82d4fd1193bcb7e44ee38838f00bf924ffa76 ## Verification - The fix commit is contained in the public v2026.4.22 tag. - openclaw@2026.4.22 is published on npm and the compiled package contains the fix. - Focused regression coverage for this path passed before publication. OpenClaw thanks @VladimirEliTokarev for reporting.
