Code Injection Vulnerability in Apache ActiveMQ Products

CVE-2026-41044

What is CVE-2026-41044?

CVE-2026-41044 is a significant code injection vulnerability affecting Apache ActiveMQ products, including Apache ActiveMQ, Apache ActiveMQ Broker, and Apache ActiveMQ All. This vulnerability arises from improper input validation, which allows an authenticated attacker to exploit the admin web console. By crafting a malicious broker name, the attacker can bypass name validation and inject remote Spring XML applications into the system. This can lead to arbitrary code execution on the broker's Java Virtual Machine (JVM), utilizing vulnerable bean factory methods to execute potentially harmful commands. Consequently, organizations using affected versions of these products are at heightened risk of unauthorized control and manipulation of their messaging services, potentially leading to severe operational disruptions and security breaches.

Potential impact of CVE-2026-41044

1. Arbitrary Code Execution: The vulnerability allows attackers to execute arbitrary code on the broker's JVM, potentially allowing them to gain full control of the messaging system and enabling further exploitation of the organization's network.

2. Data Integrity Compromise: With the ability to execute arbitrary commands, an attacker could manipulate messages, alter system configurations, or inject malicious payloads, severely compromising the integrity and reliability of data transmitted through the messaging services.

3. Operational Disruption: Exploiting this vulnerability could lead to substantial disruptions in messaging services critical for business operations. The potential to send malformed or malicious messages can impact communication channels, leading to downtime and loss of service availability.
