Real Cookie Banner < 3.4.10 is vulnerable to Contributor+ Stored XSS vulnerability

The Real Cookie Banner plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 3.4.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
