What to do now

There is no fixed version yet. If you can manage without Cincopa video and media plug-in for now, deactivate and delete it until the developer ships a fix.
If you must keep it, cut down who can log in (remove unused accounts, especially low-level ones, and turn off open registration) and put a web application firewall in front of the site.
Check the Cincopa video and media plug-in page for a fix; it updates when the CVE feeds do.
Not sure which version you run? Check your version against every known Cincopa video and media plug-in issue. With WP-CLI: wp plugin get video-playlist-and-gallery-plugin --field=version.
