| Title | ezequiroga mcp-bases c630b8ab0f970614d42da8e566e9c0d15a16414c Path Traversal |
|---|
| Description | The search_papers MCP tool reuses the caller-controlled topic string as a directory name under papers/, but it only lowercases the value and replaces spaces with underscores. Traversal markers such as ../ are preserved. As a result, a request like topic="../escape-test" causes the server to create papers/../escape-test, which resolves outside the intended storage directory, and to later read or write papers_info.json in that escaped location. The related resource handler papers://{topic} repeats the same unsafe path construction when reading topic data back. |
