CVE-2026-49362: Apache Artemis, Apache ActiveMQ Artemis: Missing Authentication in CORE Protocol Handler Allows Unauthorized Queue Creation

CVE-2026-49362: unauthenticated attackers can create arbitrary durable queues in ActiveMQ Artemis via the CORE protocol, enabling denial of service.

A missing authentication check in the CORE protocol handler of Apache Artemis and Apache ActiveMQ Artemis, tracked as CVE-2026-49362, lets unauthenticated remote attackers create arbitrary durable queues. This enables unauthorized broker state manipulation and potential denial of service. Affected versions are artemis-server in Apache Artemis 2.50.0 through 2.56.0 and ActiveMQ Artemis 1.0.0 through 2.44.0. Apache rates the issue as important.

CVE-2026-57967: Apache Artemis, Apache ActiveMQ Artemis: Missing authentication on CORE protocol session reattachment

CVE-2026-57967: unauthenticated attackers can hijack authenticated ActiveMQ Artemis sessions via crafted CORE protocol SESSION_REATTACH packets.

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 on Apache Artemis and ActiveMQ Artemis. Affected versions are artemis-server 2.50.0 through 2.56.0 in Apache Artemis and artemis-server 1.0.0 through 2.44.0 in Apache ActiveMQ Artemis. Apache rates the issue important.

CVE-2026-49363: Apache Artemis, Apache ActiveMQ Artemis: Pre-Authentication Information Disclosure in CORE Protocol Topology Subscription

CVE-2026-49363 lets unauthenticated attackers subscribe to ActiveMQ Artemis CORE topology and harvest cluster node details pre-authentication.

An unauthenticated remote attacker connecting with the CORE protocol can discover cluster node details by sending a SUBSCRIBE_TOPOLOGY request before authentication, tracked as CVE-2026-49363. The flaw affects artemis-server in Apache Artemis 2.50.0 through 2.56.0 and Apache ActiveMQ Artemis 1.0.0 through 2.44.0. Apache rates the issue as moderate; impact is limited to information disclosure of topology data.

CVE-2026-57822: Apache Artemis, Apache ActiveMQ Artemis: Message-based management parameter deserialization may lead to denial of service

Apache fixed CVE-2026-57822, a deserialization flaw in ActiveMQ Artemis management messaging letting authorized clients trigger broker denial of service.

Apache disclosed a deserialization issue in message-based management request handling for Apache Artemis and Apache ActiveMQ Artemis. It affects Apache Artemis (artemis-core-client) 2.50.0 through 2.56.0 and ActiveMQ Artemis (artemis-core-client) 1.3.0 through 2.44.0. Exploitation requires an authenticated client authorized with MANAGE permission using management-via-messaging; parameter processing can trigger denial of service. Apache rates the issue as important.

CVE-2026-75880: Apache Artemis, Apache ActiveMQ Artemis: Message selector wildcard handling could lead to denial of service

CVE-2026-75880: authenticated ActiveMQ Artemis clients can cause denial of service via crafted selector wildcard handling in affected versions.

An authenticated client can attach a consumer with a selector containing crafted wildcard usage, causing excessive evaluation during message delivery attempts that occupies a shared broker thread and leads to denial of service. Affected versions are Apache Artemis artemis-selector 2.50.0 through 2.56.0 and Apache ActiveMQ Artemis artemis-selector 1.0.0 through 2.44.0. Apache rates the issue moderate.

Google stole open source code without crediting the authors (Artemis/Minitap)

Minitap alleges Google's Artemis mobile-agent project reused its open-source mobile-use code and stripped author attribution, despite Apache 2.0 requirements.

Minitap says Google's Artemis project for automating mobile devices contains code identical to its open-source mobile-use agent, including the Hopper agent's verbatim instructions and a WhatsApp messaging example, and that a package file listing authors Pierre-Louis Favreau, Jean-Pierre Lo, and Nicolas Dehandschoewercker was replaced via an August force push removing their names. The company argues this conflicts with Apache 2.0's requirement to preserve copyright and attribution notices. Minitap also claims the AndroidWorld leaderboard ignored its later 94.8% and 100% submissions while showing Artemis at 99.1% and mobile-use at 91.4%. It has published a public factual record with archived file comparisons.
