Is this vulnerability remotely exploitable beyond the admin perimeter?

The script injection itself requires authenticated administrative access, but once malicious scripts are stored, they can execute in the browsers of any users who access the affected interface, effectively extending the impact beyond the original admin.

What level of access does an attacker need to exploit this issue?

An attacker must be able to authenticate as an administrator or otherwise gain administrative privileges that allow modification of the vulnerable configuration fields.

What is the safest general fix pattern for this vulnerability class?

Implement strict, context-aware output encoding for all user- and configuration-supplied data, combined with input validation that restricts configuration fields to safe content and blocks script-capable constructs.
