NVD description
OpenClaw versions prior to 2026.3.2 contain a race condition vulnerability in ZIP extraction that allows local attackers to write files outside the intended destination directory. Attackers can exploit a time-of-check-time-of-use race between path validation and file write operations by rebinding parent directory symlinks to redirect writes outside the extraction root.
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.
