A low-privileged user/operator injects a malicious JavaScript payload into the Department Assignment "Alias Nick" field while assigning or editing department access. When a higher-privileged user (e.g., admin or operator) edits the department assignment "Alias Nick" field, the stored script is executed in their browser context.

## Reproduction Steps:

1. Log in as an operator.
2. Navigate to your Department Assignment settings page.
3. In the "Alias Nick" field, enter the following payload:
 
   ``` "><img src="x" onerror="prompt(1);">```

4. Save the changes.
5. Revist the Department Assignment settings page and edit the Alias Nick field, the cross site scripting (xss) will execute.
