7.5 / 10

HIGH

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Description

Cloudburst Network provides network components used within Cloudburst projects. A vulnerability in versions prior to `1.0.0.CR3-20260418.124334-32` impacts publicly accessible software depending on the affected versions of Network and allows an attacker to exploit a bug in Network to close the parent netty channel, rendering it inoperable. All consumers of the library should upgrade to at least version `1.0.0.CR3-20260418.124334-32`. There are no known workarounds beyond updating the library.
