CVE-2026-45505: CWE-20 Improper Input Validation in Apache Software Foundation Apache ActiveMQ Broker
CVE-2026-45505 is a high-severity vulnerability in Apache ActiveMQ Broker involving improper input validation. Authenticated attackers can exploit the Jolokia JMX-HTTP bridge by passing crafted discovery URIs that load remote Spring XML application contexts, leading to arbitrary code execution on the broker's JVM. This affects Apache ActiveMQ Broker versions before 5.19.7 and from 6.0.0 up to but not including 6.2.6. Users are advised to upgrade to fixed versions to mitigate this risk.
AI Analysis
Technical Summary
This vulnerability in Apache ActiveMQ Broker arises from improper input validation (CWE-20) that allows authenticated users to exploit the Jolokia JMX-HTTP bridge. By supplying specially crafted discovery URIs, attackers can cause the broker to load remote Spring XML application contexts, resulting in arbitrary code execution within the broker's JVM. The affected versions include all versions prior to 5.19.7 and versions starting at 6.0.0 but before 6.2.6. The CVSS v3.1 base score is 8.8, indicating high severity with network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows authenticated attackers to execute arbitrary code on the Apache ActiveMQ Broker JVM, potentially leading to full compromise of the broker, including unauthorized control over message processing and broker operations. The impact includes high confidentiality, integrity, and availability loss.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should upgrade Apache ActiveMQ Broker to versions 5.19.7 or later, or 6.2.6 or later, once available. Until a patch is confirmed, restrict access to the Jolokia JMX-HTTP bridge to trusted users only and monitor for suspicious activity involving discovery URIs.
