Description

OpenClaw versions prior to 2026.2.21 contain an approval-integrity mismatch vulnerability in system.run that allows authenticated operators to execute arbitrary trailing arguments after cmd.exe /c while approval text reflects only a benign command. Attackers can smuggle malicious arguments through cmd.exe /c to achieve local command execution on trusted Windows nodes with mismatched audit logs.
