Summary
OpenShell FS bridge reads pin and verify the opened file before returning bytes
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 reads could let a symlink swap cause bytes outside the intended mount root to be read.
Fix
OpenShell reads now open the file with no-follow semantics where available, validate the pinned file descriptor against the canonical mount root, reject unsafe hardlink/symlink cases, and use a strict fallback ancestor walk on platforms without fd-path readback.
