CVSS 3.1 - 3.8
Vector String: AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N
Vector Clarification:
- User interaction is not required as the admin console is regularly used during an administrator's work
- The scope is unchanged since the admin console web application is both the vulnerable component and where the exploit executes
