CVE-2026-7314 Details
Description
A vulnerability was detected in eiceblue spire-doc-mcp-server 1.0.0. This affects the function get_doc_path of the file src/spire_doc_mcp/api/base.py. Performing a manipulation of the argument document_name results in path traversal. The attack can be initiated remotely. The exploit is now public 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 Eiceblue Spire.Doc MCP Server version 1.0.0. The issue arises in the 'get_doc_path' function within 'src/spire_doc_mcp/api/base.py', where the 'convert_document' tool improperly handles the 'output_path' parameter. This oversight allows for arbitrary file writes outside the designated 'WORD_FILES_PATH' directory. The vulnerability can be exploited remotely, and the details of the exploit are publicly available.
To address this vulnerability, the 'output_path' parameter should be sanitized to prevent directory traversal and ensure it remains within the 'WORD_FILES_PATH' directory. Additionally, the MCP server should be restricted to trusted callers until a patch is implemented.
