CVE-2026-7788 Details
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.
A path traversal vulnerability has been identified in Axle-Bucamp MCP-Docusaurus versions prior to commit 404bc028e15ec304c9a045528560f4b5f27a17e0. The issue arises in the document management functions of the FastAPI application, specifically within 'app/routes/document.py'. The vulnerability allows for manipulation of the 'path' argument, enabling attackers to traverse directories and access files outside the intended documentation root. This could lead to unauthorized reading, modification, or deletion of files, depending on the existence and type of the targeted file.
The vulnerability can be addressed by applying canonical path validation to all document-related functions that perform file operations. This includes enforcing strict containment checks before reading, writing, or deleting files, and rejecting traversal patterns, absolute paths, and symlink escape scenarios.
