The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Page Builder Text Content in all versions up to, and including, 6.2.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with kirki_content_access capability granted by an administrator, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
