## Affected

- widgetpack Rich Showcase for Google Reviews: through 7.1.6

## Description

The Rich Showcase for Google Reviews plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.1.6 This is due to the plugin not properly verifying that a user is authorized to perform an action.
