CVE-2026-49364

Artemis and JGroups lack of access controls in certain situations can allow an attacker to spoof a password request in JGroups and subsequently gain access to the cluster. This allows the attacker manage-level authority for provided messaging and queue operations...

CVE-2026-57967

in Apache Artemis, the REATTACHSESSION 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...
