Vulnerability from github – Published: 2026-04-28 15:30 – Updated: 2026-04-28 15:30

Details

A flaw has been found in WilliamCloudQi matlab-mcp-server up to ab88f6b9bf5f36f725e8628029f7f6dd0d9913ca. The affected element is the function generate_matlab_code/execute_matlab_code of the file src/index.ts of the component MCP Interface. Executing a manipulation of the argument scriptPath can lead to path traversal. The attack can be executed remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
