subscriber role and above to store JavaScript that executes in the browser of an administrator who opens the YayPricing

You are affected if your site runs subscriber role and above to store JavaScript that executes in the browser of an administrator who opens the YayPricing. Versions below 3.5.7 are vulnerable; that release and later are not. An attacker needs any registered account, so open registration materially increases the risk.

Q: How do I fix it?

Update subscriber role and above to store JavaScript that executes in the browser of an administrator who opens the YayPricing to version 3.5.7 or later. That is the complete fix.
