Оригинално описание
The Apache Pulsar broker exposes a transaction administration REST API under /admin/v3/transactions. When authentication and authorization are enabled, most of the read endpoints of this API verify only that the request is authenticated and that the broker serves the requested topic or transaction coordinator. They do not check whether the caller is permitted to access the tenant, namespace or topic whose data is returned. The endpoints that modify state, which abort a transaction or scale the transaction coordinators, correctly require super-user access and are not affected. As a result, any authenticated user, including one that has been granted no permissions, can read transaction coordinator and transaction information belonging to other tenants. This includes the list of transaction coordinators with the broker service URLs that serve them, transaction coordinator statistics and internal statistics, transaction metadata including the names of the topics and subscriptions a transaction involves and the principal that opened it, the list of long-running transactions on a transaction coordinator, transaction buffer and pending acknowledgement statistics and internal statistics for any topic and subscription, and whether a given message position of a subscription is currently held in a pending transactional acknowledgement. The disclosure of transaction metadata and statistics can only occur when transaction support is enabled in the broker (transactionCoordinatorEnabled, which is disabled by default). When transaction support is disabled, these endpoints return no transaction data; the only residual effect is that one endpoint's error response can reveal whether a named topic exists in another tenant. The impact is limited to disclosure of transaction-related metadata and statistics across tenant boundaries. The issue does not allow reading message contents, modifying or aborting transactions, or changing any configuration. This issue affects Apache Pulsar ver
