Executive Summary

Hulumi versions before v1.3.2 have a vulnerability where helper scripts are resolved from an unsafe root directory. This allows workspace files to shadow the intended helper script, enabling attackers to place malicious files in the workspace. These files can then execute arbitrary code during local skill execution.

Detection Guidance

Check Hulumi version with 'hulumi --version' or inspect installed package metadata. Compare against v1.3.2. Look for unexpected helper scripts in workspace directories that may shadow the intended threat-model helper.

Impact Analysis

This vulnerability allows attackers to execute arbitrary code on your system by placing malicious files in the workspace. This could lead to unauthorized access, data theft, or system compromise during local skill execution.

Mitigation Strategies

Upgrade Hulumi to version 1.3.2 or later immediately. Remove any suspicious files in workspace directories that could shadow helper scripts. Verify helper script resolution paths after upgrade.
