NVD description
OpenClaw before 2026.4.8 contains an approval-timeout fallback mechanism that bypasses strictInlineEval explicit-approval requirements on gateway and node exec hosts. Attackers can exploit this timeout fallback to execute inline eval commands that should require explicit user approval, circumventing the intended security boundary.
What to do
- Upgrade OpenClaw to
2026.4.8or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
