Description
The Tickera – Sell Tickets & Manage Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'price_wrapper' Shortcode Attribute in all versions up to, and including, 3.6.0.0 due to insufficient input sanitization and output escaping. 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. Successful execution of the injected script is limited to victims who have the referenced ticket ID present in their cart cookie, meaning the payload only fires for users who have previously added that ticket to their cart.
