Vulnerability in jetmonsters Getwid – Gutenberg Blocks

[ Description ]Official description

The Getwid – Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Google Maps block's 'customStyle' attribute in all versions up to, and including, 2.1.3. This is due to the use of eval() on user-controlled block content in the frontend JavaScript mapStyles() function. 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.
