| Titre | duartium papers-mcp-server 0.1.0 Path Traversal |
|---|
| Description | The search_papers() MCP tool uses the caller-controlled topic string to derive a directory name under papers/, but it only lowercases the string and replaces spaces with underscores. Traversal sequences and path separators survive unchanged. The server then creates the directory and writes papers_info.json inside it. A topic such as ../../../../tmp/papers_poc therefore escapes the intended papers/ workspace and creates or overwrites /tmp/papers_poc/papers_info.json. |
