Description
The WCFM Marketplace plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the store video banner in all versions up to, and including, 3.8.3 due to the banner embed replacing only the YouTube URL inside the value and printing the rest of it without escaping. This makes it possible for authenticated attackers with vendor-level access to inject arbitrary web scripts that execute whenever a user visits the store page or the store list.
