Giveaways and Contests by RafflePress – Get More Website Traffic, Email Subscribers, and Social Followers <= 1.12.13 - Authenticated (Editor+) Stored Cross-Site Scripting

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 the Giveaway Description value in all versions up to, and including, 1.12.13 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level access, 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.
