OpenClaw < 2026.4.8 - strictInlineEval Approval Boundary Bypass via Approval-Timeout Fallback

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.
