CVE-2024-29834: Apache Pulsar: Improper Authorization For Namespace
and Topic Management Endpoints


Affected versions:

     Apache Pulsar 2.7.1 through 2.10.6
     Apache Pulsar 2.11.0 through 2.11.4
     Apache Pulsar 3.0.0 before 3.0.4
     Apache Pulsar 3.1.0 through 3.1.3
     Apache Pulsar 3.2.0 before 3.2.2

Description:

This vulnerability allows authenticated users with produce or consume
permissions to perform unauthorized operations on partitioned topics,
such as unloading topics and triggering compaction. These management
operations should be restricted to users with the tenant admin role or
superuser role. An authenticated user with produce permission can
create subscriptions and update subscription properties on
partitioned topics, even though this should be limited to users with
consume permissions. This impact analysis assumes that Pulsar has been
configured with the default authorization provider. For custom
authorization providers, the impact could be slightly different.
Additionally, the vulnerability allows an authenticated user to read,
create, modify, and delete namespace properties in any namespace in
any tenant. In Pulsar, namespace properties are reserved for user
provided metadata about the namespace.

This issue affects Apache Pulsar versions from 2.7.1 to 2.10.6, from
2.11.0 to 2.11.4, from 3.0.0 to 3.0.3, from 3.1.0 to 3.1.3, and
from 3.2.0 to 3.2.1.

3.0 Apache Pulsar users should upgrade to at least 3.0.4.
3.1 and 3.2 Apache Pulsar users should upgrade to at least 3.2.2.

Users operating versions prior to those listed above should upgrade
to the aforementioned patched versions or newer versions.
