As published by the source; long descriptions are shortened.

Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. Non-parenthesized discovery wrappers such as masterslave:vm://...,... and static:vm://... incorrectly pass validation allowing bypass of fix in CVE-2026-34197. Original description from CVE-2026-34197. Apache ActiveMQ 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 UR 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…

# Patch Next advisory brief: CVE-2026-45505

Advisory: Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ have a Code Injection issue
IDs: CVE-2026-45505, GHSA-v853-w46p-fv2h
Record: https://patchnext.com/advisories/cve-2026-45505 (revision 1, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.activemq:activemq-broker 6.2.6, 5.19.7; org.apache.activemq:apache-activemq 6.2.6, 5.19.7; org.apache.activemq:activemq-all 6.2.6, 5.19.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.activemq:activemq-broker: affected < 5.19.7; >= 6.0.0, < 6.2.6; fixed in 6.2.6, 5.19.7
- Maven org.apache.activemq:apache-activemq: affected < 5.19.7; >= 6.0.0, < 6.2.6; fixed in 6.2.6, 5.19.7
- Maven org.apache.activemq:activemq-all: affected < 5.19.7; >= 6.0.0, < 6.2.6; fixed in 6.2.6, 5.19.7

## Suggested inspection (read-only)
- Maven org.apache.activemq:activemq-broker: check the installed version with your package manager.
- Maven org.apache.activemq:apache-activemq: check the installed version with your package manager.
- Maven org.apache.activemq:activemq-all: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.activemq:activemq-broker, org.apache.activemq:apache-activemq, org.apache.activemq:activemq-all.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
