Technical Analysis
CVE-2026-49877 describes an improper authorization vulnerability in Apache ActiveMQ's Web Console. By default, the Jetty server settings do not restrict access to /admin/* paths exclusively to admin users, allowing authenticated users with low privileges to access administrative functions. This affects Apache ActiveMQ versions prior to 5.19.8 and versions from 6.0.0 up to but not including 6.2.7. The issue is resolved by upgrading to version 5.19.8 or 6.2.7 and later.
Potential Impact
An authenticated user with low privileges can access administrative paths in the Web Console, potentially leading to unauthorized administrative actions. The CVSS score of 8.1 indicates high impact on confidentiality and integrity, but no impact on availability.
Mitigation Recommendations
Upgrade Apache ActiveMQ to version 5.19.8 or 6.2.7 or later, where the improper authorization issue is fixed. No other mitigation is specified or recommended.
