Recommendation: Monitor — no exploitation signal at the moment.
The Schedulicity WordPress plugin through 2.21 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.
