Privilege escalation in rbac

Details

Impact

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.

Patches

The issue has been fixed in 0.24.0 and 0.23.1.

Workarounds

For users who are unable to upgrade, we recommend auditing users who have UserWrite permissions and regularly reviewing the Event Log for malicious activity.
