Short explanation

Apache ActiveMQ and Apache ActiveMQ Runtime Config contain an improper authorization caching invalidation vulnerability where write access is retained after live ACL revocation. Due to improper invalidation of cached authorizations, authenticated connections opened prior to the change can continue sending data to the destination.

Why does it matter?

This vulnerability allows existing connections to continue transmitting unauthorized data even after a principal's write privileges are removed. It prevents the real-time enforcement of security policies and access control lists.

What should be done?

  • Upgrade Apache ActiveMQ and Runtime Config to versions 6.4.0, 6.3.3, or 5.19.12
  • Follow vendor advisory guidance for updates
