CVE-2026-110020: Rich Showcase for Google Reviews <= 7.1.6 - Missing Authorization to Authenticated (Contributor+) Site Secret Disclosure via 'grw_auth_code' Site Secret Disclosure via grw-builder Admin Page

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