Azure CycleCloud Elevation of Privilege Vulnerability

How could an attacker exploit this vulnerability?
An authenticated user who has the Cluster Creator role could exploit this vulnerability by using a cluster creation operation in a way that bypasses an authorization check. By doing so, the attacker could overwrite another user’s cluster, including a cluster owned by an administrator, and take ownership of it.

What privileges could be gained by an attacker who successfully exploited the vulnerability?
An attacker who successfully exploited this vulnerability could gain full control of the affected cluster that was overwritten and taken over. This could allow the attacker to run unauthorized code, remove or alter credentials associated with the cluster, and perform actions with the same level of access available within that cluster.
