Official description
The Reviews and Rating – Google Reviews plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 5.10. This is due to the wp_display() shortcode handler, used by multiple shortcodes, allowing attacker-controlled html_tags values to define raw HTML tags and then embedding untrusted vicinity content inside those tags. 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.
