CVE-2026-15751 Details
Description
A security vulnerability has been detected in mastergo-design mastergo-magic-mcp up to 0.2.0. The affected element is the function execute of the file mastergo/component-workflow.md of the component mcp__getComponentGenerator. The manipulation of the argument rootPath leads to path traversal. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A path traversal vulnerability has been identified in the Mastergo-Design Mastergo-Magic-MCP tool, specifically in versions up to 0.2.0. The issue arises within the 'mcp__getComponentGenerator' function, where the 'rootPath' argument is not properly validated. This flaw allows for the creation of directories and files in an attacker-specified location under the '.mastergo/' directory. The vulnerability requires local exploitation, and although it has been publicly disclosed, the project maintainers have not yet addressed it.
Users are advised to update to version 0.2.3 or later, where this vulnerability has been addressed.
