NVD description
OpenClaw versions prior to 2026.2.2 contain an exec approvals (must be enabled) allowlist bypass vulnerability that allows attackers to execute arbitrary commands by injecting command substitution syntax. Attackers can bypass the allowlist protection by embedding unescaped $() or backticks inside double-quoted strings to execute unauthorized commands.
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.
