Quick assessment

Affected
Apache Software Foundation Apache Artemis
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

已认证的客户端可以添加一个带有精心构造的通配符选择器（selector）的消费者，该选择器在消息投递尝试期间会导致过多的求值，从而占用共享的 Broker 线程，进而导致拒绝服务（DoS）。 此问题影响 Apache Artemis 的 2.50.0 至 2.56.0 版本；以及 Apache ActiveMQ Artemis 的 1.0.0 至 2.44.0 版本。 建议用户升级至 2.57.0 版本，该版本已修复此问题。
