Privilege escalation in rbac
Using a carefully crafted request or malicious proxy, a user with
UserWrite permissions could create another user with higher privileges than their own due to insufficient checks on the allowed set of permissions. The event would be captured in the Event Log.
The issue has been fixed in 0.24.0 and 0.23.1.
For users who are unable to upgrade, we recommend auditing users who have
UserWrite permissions and regularly reviewing the Event Log for malicious activity.
