Title

donchelo processing-claude-mcp-bridge create_sketch Tool processing_server.py path traversal

Summary

A weakness has been identified in donchelo processing-claude-mcp-bridge up to e017b20a4b592a45531a6392f494007f04e661bd. Impacted is an unknown function of the file processing_server.py of the component create_sketch Tool. This manipulation of the argument sketch_name causes path traversal. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.
