- openclaw (npm): fixed in 2026.3.8

## Description

OpenClaw before 2026.3.8 contains an approval bypass vulnerability in system.run where mutable script operands are not bound across approval and execution phases. Attackers can obtain approval for script execution, modify the approved script file before execution, and execute different content while maintaining the same approved command shape.

## What to do
