DescriptionThe 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. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve the plugin's 127-character site-wide grw_auth_code authentication secret and use it to impersonate the WordPress site to the RichPlugins backend service at app.richplugins.com.
