Custom Base Terms < 1.0.3 - Admin+ Stored XSS

The plugin does not sanitize and escape some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

The options in the plugin settings are vulnerable to the following XSS payload:

`"><script>alert(1)</script>`

Enter the PoC in any of the settings and reload to see the XSS.
