NVD description
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.
What to do
- Upgrade OpenClaw to
2026.3.11or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
