Description
The Vidplex plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the font family attributes of the Grid Carousel and Channel Details blocks in all versions up to, and including, 1.0.3, due to insufficient input sanitization and output escaping. The raw font family values are put into a Google Fonts URL that is echoed inside a link tag's href attribute without escaping or URL encoding. 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 a page containing the block.
