Recommendation: Monitor — no exploitation signal at the moment.

The WPUpper Share Buttons WordPress plugin through 3.42 does not sanitise 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).
