Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Artemis artemis-openwire-protocol versions 2.50.0 through 2.52.0 and org.apache.activemq artemis-openwire-protocol versions 2.0.0 through 2.44.0 are affected. An authenticated user with the createDurableQueue permission but without createAddress can, when address auto-creation is disabled, create a temporary address by attempting a non-durable JMS topic subscription over OpenWire, which should have been refused. The temporary address is removed when the connection closes. Upgrade to version 2.53.0, which fixes the issue.
