Hello CMSMS Team,

I am reaching out to report a Stored XSS vulnerability via File picker feature
from CMS Made Simple version 2.2.10. An attacker can create a new profile and
add payload into "Name" field.
Steps to reproduce:
- Navigate to Admin Dashboard
- Click on Extension -> File Picker feature
- Click on "Add a new Profile"
- In "Name" field, input payload: <svg/onload=alert(document.domain)>
- Click "Submit"
- After submitting, payload will be executed every time we refresh "File Picker"
page.

Impact:
- An attacker will be able to take over an account as well as cookies hijacking.
