Vulnerability Description
The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's extend_builder_render_js shortcode in all versions up to, and including, 1.0.239 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
