Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Ray versions up to and including 2.52.0 have token authentication for the dashboard and Jobs API disabled by default. A remote attacker with network access to these interfaces can submit jobs and run arbitrary code on the cluster. No fixed version is listed; the vendor recommends setting RAY_AUTH_MODE=token to enable token authentication.
