Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Druid versions below 31.0.2, and versions from 32.0.0 before 32.0.1, are affected. An authenticated user can send a specially crafted URL through the Druid management proxy to redirect requests to an arbitrary server, which can enable cross-site scripting or cross-site request forgery. Upgrade to Apache Druid 31.0.2 or 32.0.1. Disabling the management proxy mitigates the issue, though some web console features will stop working.
