CVE-2026-50750: Denial of Service via Out of Memory in Apache Software Foundation Apache ActiveMQ Broker
CVE-2026-50750 is a denial of service vulnerability in Apache ActiveMQ Broker that allows an unauthenticated attacker to cause an out of memory (OOM) condition. This occurs when the attacker sends repeated BrokerInfo commands without sending a ConnectionInfo, leading the broker to crash due to memory exhaustion. The issue affects Apache ActiveMQ Broker versions from 5.19.7 before 5.19.8 and from 6.2.6 before 6.2.7. Users are advised to upgrade to version 6.2.7 to address this vulnerability.
AI Analysis
Technical Summary
Following the fix for CVE-2026-49270, an unauthenticated attacker can exploit a flaw in Apache ActiveMQ Broker by sending repeated BrokerInfo commands without accompanying ConnectionInfo messages. This triggers an out of memory condition in the broker, causing it to crash and resulting in a denial of service. The vulnerability affects Apache ActiveMQ Broker versions 5.19.7 up to but not including 5.19.8, and 6.2.6 up to but not including 6.2.7. The recommended remediation is to upgrade to version 6.2.7, which contains the fix.
Potential Impact
An unauthenticated attacker can cause the Apache ActiveMQ Broker to exhaust its memory resources by sending repeated BrokerInfo commands without ConnectionInfo, leading to a denial of service via broker crash. This disrupts message broker availability and may impact dependent applications and services relying on ActiveMQ for messaging.
Mitigation Recommendations
Users should upgrade affected Apache ActiveMQ Broker installations to version 6.2.7 or later, which fixes this out of memory vulnerability. No alternative mitigations or temporary workarounds are indicated in the available data.
