NVD description
OpenClaw before 2026.4.10 contains a time-of-check-time-of-use vulnerability in the validateScriptFileForShellBleed function that allows local attackers to bypass workspace boundary checks. An attacker with workspace write access can race-condition swap the target file between validation and preflight read, causing the validator to inspect a different file identity than the one that passed the initial boundary check.
What to do
- Upgrade OpenClaw to
2026.4.10or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
