Structured Content < 1.6.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Classic Editor Shortcode

Description

The Structured Content plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Classic Editor shortcodes in all versions up to, and including, 1.6.1 due to insufficient input sanitization and output escaping. 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.
