The If-So Dynamic Content – Elementor & All Page Builders Personalization plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'repeater[*][version_uid] (and many sibling fields: freeze-mode, cookie-input, ip-input, compare, utm-value, page-url-compare, group-name, custom, …)' parameter in all versions up to, and including, 1.10.2 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.
