Description
Cloudburst Network provides network components used within Cloudburst projects. A vulnerability in versions prior to `1.0.0.CR3-20260417.085727-30` impacts publicly accessible software depending on the affected versions of Network and allows an attacker to exploit a vulnerability in Network to stall the netty event loop, rendering it inoperable.
