NVD description
OpenClaw versions prior to 2026.3.2 contain an archive extraction vulnerability in the tar.bz2 installer path that bypasses safety checks enforced on other archive formats.

What to do
- Upgrade OpenClaw to
2026.3.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
