CVE-2026-7788

Description

A security flaw has been discovered in Axle-Bucamp MCP-Docusaurus up to 404bc028e15ec304c9a045528560f4b5f27a17e0. The affected element is the function update_document/continue_document/delete_document/get_content of the file app/routes/document.py. Performing a manipulation of the argument DOCS_DIR/path results in path traversal. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.
