What to do

There is no fixed version yet. If you can live without Filestack for now, deactivate it and delete it until the developer ships a fix.
If you must keep it, limit who can log in (remove unused accounts, especially low-level ones) and put a web application firewall in front of the site.

Details from the advisory

The Filestack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'filepicker' shortcode in all versions up to, and including, 2.0.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
