CVE-2026-49877Network attack vector

Authenticated privilege escalation via unrestricted admin paths

Published Jun 30, 2026 · Updated Jun 30, 2026

Improper authorization in Apache ActiveMQ before 5.19.8 and 6.0.0 through 6.2.6 allows remote authenticated users to access admin paths. The default Jetty security constraints authenticate Web Console users but do not restrict /admin/* to the admins role. Any low-privilege Web Console account can therefore reach administrative functions, enabling unauthorized reads and changes through the broker management interface.
