  "details" : [ "An unauthenticated remote attacker can craft a CORE protocol SESSION_REATTACH packet to steal an existing session and assume ongoing execution of the previously authenticated session.\nThis issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0.\nUsers are recommended to upgrade to version 2.57.0, which fixes the issue.", "in Apache Artemis, the REATTACH_SESSION handler performs zero authentication — it looks up the session by name only and calls transferConnection() unconditionally, migrating the authenticated session to the attacker's connection. The hijacked cluster-bridge session inherits full broker-management authority (message injection, topology manipulation, journal access)" ],
