Is CVE-2026-57822 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-57822 is not in the CISA KEV catalog (checked ) and no tracked advisory for it reports exploitation. That is not proof the vulnerability cannot be exploited.

How do I fix CVE-2026-57822?

Upgrade to a fixed release named by the vendor:

  • Apache: 2.57.0
  • Red Hat: 2.57.0, artemis-core-client, RHSA-2026:66545, RHSA-2026:66488
  • Users are recommended to upgrade to version 2.57.0, which fixes the issue. (Apache)
  • Restrict MANAGE role access: ensure only trusted administrative accounts have the manage permission on the activemq.management address. Review security-setting configurations in standalone-full.xml (EAP) or broker.xml (AMQ Broker) to confirm management address role assignments follow least-privilege principles. Additionally, restrict network access to messaging ports (default 61616) so that management operations are only accessible from administrative networks. (Red Hat)

    Medium [CVE-2026-57822] Unsafe deserialization via JsonUtil CompositeData on management address

    CVE-2026-57822Source published Source updated

    When the broker is processing message-based management requests, sent by an authenticated messaging client that is authorized with MANAGE permission to perform management-via-messaging, the parameter processing can trigger Java deserialization of certain method parameters that the broker will not utilise. The permitted types allow to craft a payload causing excessive computation and pinning the processing thread, leading to denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.3.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue. The JsonUtil.fromJsonArray() method uses ObjectInputStream.readObject() to deserialize CompositeData from Base64-encoded serialized objects in management message…
