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. The project was informed of the problem early through an issue report but has not responded yet.",
