CVE-2026-49877: Apache ActiveMQ

High severity, CVSS 8.1. EPSS: 0.5% chance of exploitation in the next 30 days.

Improper Authorization vulnerability in Apache ActiveMQ. An authenticated low-privilege Web Console user by default can access /admin/* paths in the Web Console. The default Jetty settings incorrectly did not limit those paths to only admins. This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7. Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.

Affected products

• Apache ActiveMQ: before 5.19.8 (fixed in 5.19.8); from 6.0.0, before 6.2.7 (fixed in 6.2.7)
