Enviar #803083: elie mcp-project 0.1.0 Path Traversalinformación

Títuloelie mcp-project 0.1.0 Path Traversal
DescripciónMCP Research Server stores arXiv search results under PAPER_DIR = "papers". The search_papers(topic, max_results) tool incorrectly reuses the caller-controlled topic string as a filesystem directory name: path = os.path.join(PAPER_DIR, topic.lower().replace(" ", "_")) file_path = os.path.join(path, "papers_info.json") Because the code only lowercases the string and replaces spaces, traversal sequences such as ../ remain intact. A malicious topic therefore escapes the intended papers/ directory and causes the server to create or overwrite papers_info.json in an attacker-chosen location on the host.
