Evidence used

  • CISA confirms exploitation in the wild.
  • EPSS is 15.49% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Apache ActiveMQ and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Summary
A flaw was found in Apache ActiveMQ Broker and Apache ActiveMQ. An authenticated attacker can exploit this vulnerability by sending a specially crafted discovery Uniform Resource Identifier (URI) to the Jolokia JMX-HTTP bridge, which is exposed on the web console. This allows the attacker to bypass configuration validation and load a remote Spring XML application context. Consequently, this leads to arbitrary code execution on the broker's Java Virtual Machine (JVM).

CISA KEV mirrored by ENISA

Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ. Apache ActiveMQ Classic exposes the Jolokia JMX-HTTP bridge at /api/jolokia/ on the web console. The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including BrokerService.addNetworkConnector(String) and BrokerService.addConnector(String). An authenticated attacker can invoke these operations with a crafted discovery URI that triggers the VM transport's brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ Broker: before 5.19.4, from 6.0.0 before 6.2.3; Apache ActiveMQ All: before 5.19.4, from 6.0.0 before 6.2.3; Apache ActiveMQ: before 5.19.4, from 6.0.0 before 6.2.3. Users are recommended to upgrade to version 5.19.4 or 6.2.3, which fixes the issue

01

What, why and how

Apache ActiveMQ contains an improper input validation vulnerability that allows for code injection.

What

Apache ActiveMQ contains an improper input validation vulnerability that allows for code injection.

Why

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2026-04-16.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

Apache ActiveMQ BrokerおよびApache ActiveMQにおける不適切な入力検証および不適切なコード生成制御（コードインジェクション）の脆弱性です。Apache ActiveMQ Classicは、Webコンソールの/api/jolokia/にJolokia JMX-HTTPブリッジを公開しています。デフォルトのJolokiaアクセスポリシーは、BrokerService.addNetworkConnector(String)やBrokerService.addConnector(String)を含むすべてのActiveMQ MBeans（org.apache.activemq:*）に対するexec操作を許可しています。認証された攻撃者は、VMトランスポートのbrokerConfigパラメータがResourceXmlApplicationContextを使用してリモートのSpring XMLアプリケーションコンテキストをロードする仕組みを悪用した細工されたdiscovery URIを介して、これらの操作を呼び出すことができます。SpringのResourceXmlApplicationContextは、BrokerServiceが設定を検証する前にすべてのシングルトンBeanをインスタンス化するため、Runtime.exec()などのBeanファクトリーメソッドを通じてブローカーのJVM上で任意のコードを実行します。この問題はApache ActiveMQ Brokerバージョン5.19.4以前、6.0.0から6.2.3未満のバージョン、Apache ActiveMQ全体の同バージョンに影響があります。ユーザーはこの問題を修正したバージョン5.19.4または6.2.3へのアップグレードを推奨します。
