HurryTimer <= 2.11.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Campaign Name

The HurryTimer – An Scarcity and Urgency Countdown Timer for WordPress & WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.11.2 due to insufficient input sanitization and output escaping of a campaign name. 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.
