Apache Pulsar input validation error vulnerability

Apache Pulsar is an Apache Foundation distributed messaging platform for cloud environments that integrates messaging, storage, and lightweight functional computing. The software supports multi-tenancy, persistent storage, multi-room cross-regional data replication, and highly scalable streaming data storage with strong consistency, high throughput, and low latency.Apache Pulsar suffers from an input validation error vulnerability that stems from a network system or product that does not properly validate input data. An attacker could exploit this vulnerability to access data from BookKeeper on topics that are accessible to unauthenticated users.
