CVE-2026-42423

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

State: Published
Severity: 7.7 High
Published: Apr 28, 2026
Updated: Apr 30, 2026
Reserved: Apr 27, 2026

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.
