## Overview

OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in the fs-bridge writeFile commit step that uses an unanchored container path during the final move operation. An attacker can exploit a time-of-check-time-of-use race condition by modifying parent paths inside the sandbox to redirect committed files outside the validated writable path within the container mount namespace.

## Affected

- `openclaw < 2026.3.11`

## Remediation

Upgrade past the affected range:

- `openclaw 2026.3.11`
