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.
