## Overview

OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in fs-bridge staged writes where temporary file creation and population are not pinned to a verified parent directory. Attackers can exploit a race condition in parent-path alias changes to write attacker-controlled bytes outside the intended validated path before the final guarded replace step executes.

## Affected

- `openclaw < 2026.3.11`

## Remediation

Upgrade past the affected range:

- `openclaw 2026.3.11`
