OpenClaw: Sandbox escape via TOCTOU race in remote FS bridge readFile

## 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: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31` ## Fix Commit(s) - `121870a08583033ed6a0ed73d9ffea32991252bb` — 2026-03-31T09:55:51+09:00 OpenClaw thanks @AntAISecurityLab for reporting.
