## Affected

- widgetpack Rich Showcase for Google Reviews: through 3.1

## Description

This plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode in all versions up to, and including, 3.1 due to insufficient input sanitization and output escaping on the 'place_id' attribute. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
