Giveaways and Contests by RafflePress < 1.12.17 is vulnerable to Admin+ Stored XSS vulnerability

The Giveaways and Contests by RafflePress – Get More Website Traffic, Email Subscribers, and Social Followers plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.12.16 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with admin-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
