Widgets for Google Reviews < 13.3.1 - Editor+ Stored Cross-Site Scripting via fomo-title and fomo-text Parameters

Description

The plugin is vulnerable to Stored Cross-Site Scripting via admin settings due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Editor-level access and above, 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.
