SiteOrigin Widgets Bundle <= 1.60.0 - - Authenticated (Contributor+) Stored Cross-Site Scripting via 'siteorigin_widget' Shortcode

The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'siteorigin_widget' shortcode in all versions up to, and including, 1.60.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
