Recommendation: Monitor — no exploitation signal at the moment.
The USM-Premium WordPress plugin before 16.3 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).
