CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This vulnerability is a path traversal issue in the mastergo-design mastergo-magic-mcp software up to version 0.2.0. It exists in the execute function of the file mastergo/component-workflow.md within the mcp__getComponentGenerator component. The flaw allows manipulation of the rootPath argument to access unauthorized file system paths.

Detection Guidance

Since this vulnerability involves path traversal in the mastergo-magic-mcp component, check for unusual file access patterns or unauthorized directory traversals in logs. Inspect the execute function of mastergo/component-workflow.md for suspicious rootPath arguments. No specific commands are provided in the context.

Impact Analysis

An attacker could exploit this to read sensitive files on the local system where the software runs. Since the attack requires local access, it may allow unauthorized data exposure or system manipulation depending on the privileges of the running application.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR or HIPAA if personal or health information is exposed. Organizations using the affected component may face regulatory penalties or reputational damage.

Mitigation Strategies

Immediately update mastergo-magic-mcp to a patched version if available. If no patch exists, restrict local access to the component and monitor for suspicious activity. Disable the mcp__getComponentGenerator function if not required. The project has not responded, so consider alternative solutions.
