At a Glance
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

When Open Source is a bit too OpenSeveral fun modules landed this week, including an Apache RCE, Windows Kernel pointer collection, and Gogs RCE via naming. Leading off is Gogs' RCE that allows an attacker to execute commands by naming their branch --exec and requesting a rebase.Another useful post module by CharlesQuinnDev enumerates the Kernel pointers leaked via the popular NtQuerySystemInformation technique. Those exposed pointers, combined with a good write primitive, make local privilege escalation easier to accomplish. Several local privilege escalations already use that technique, so exposing just that technique was a great call!New module content (3)Apache ActiveMQ RCE via Jolokia addNetworkConnectorAuthors: dinosn and h00dieType: ExploitPull request: #21497 contributed by h00diePath: multi/http/apache_activemq_jolokia_rceAttackerKB reference: CVE-2026-34197Adds a new exploit module exploit/multi/http/apache_activemq_jolokia_rce targeting CVE-2026-34197 in Apache ActiveMQ. The module abuses the Jolokia JMX-over-HTTP API exposed at /api/jolokia/ by calling the addNetworkConnector() MBean operation with a crafted brokerConfig=xbean:http://... URI. ActiveMQ fetches the attacker-controlled URL and instantiates it as a Spring XML application context, achieving remote code execution via a java.lang.ProcessBuilder bean.
