NVD description
OpenClaw versions prior to 2026.2.2 fail to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests (non-default configuration), allowing attackers to bypass command approval restrictions. Remote attackers can craft command strings with shell metacharacters like & or %...% to execute unapproved commands beyond the allowlisted operations.
What to do
- Upgrade OpenClaw to
2026.2.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
