CVE-2026-111822: Apache ActiveMQ improper authorization cache invalidation

CVE-2026-111822 · Severity: info · Published 2026-11-04

Apache ActiveMQ is a message broker that manages communication between applications. This vulnerability allows authenticated users to keep sending messages to destinations even after their write permissions have been revoked, bypassing the newly enforced access controls. An attacker with a pre-existing connection can continue to exploit this for unauthorized message transmission, including through anonymous producers.

Technologies: Apache ActiveMQ. Vendors: Apache.

How to fix

Fixed in: ActiveMQ 6.4.0, 6.3.3, 5.19.12

Technical details

The runtime configuration plugin fails to invalidate cached authorization grants when a principal's write permission on a destination is removed. Authenticated connections established before the policy change retain their cached grants and can continue to send messages, while fresh connections and new explicit producers correctly enforce the updated policy. This affects both ActiveMQ and the Runtime Config component across multiple version branches.

Affected products

Apache ActiveMQ 6.0.0 before 6.3.3, before 5.19.12
