Summary
Sandbox escape via TOCTOU race in remote FS bridge readFile
Current Maintainer Triage
• Normalized severity: critical
• Assessment: v2026.3.28 remote sandbox reads still do path-check then separate file read, so the TOCTOU sandbox escape remains present in the latest shipped tag.
Affected Packages / Versions
• Package: `openclaw` (npm)
• Latest published npm version: `2026.3.31`
• Vulnerable version range: `= 2026.3.31`
• First stable tag containing the fix: `v2026.3.31`
