Description

A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a user on a managed cluster to escalate their privileges by creating a Subscription with specific, crafted annotations. Successful exploitation grants the attacker the ability to deploy resources into any namespace with the elevated permissions of the controller's Service Account, potentially leading to unauthorized access and control over cluster resources.
