CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Summary
The Avada (Fusion) Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple shortcodes in all versions up to, and including, 3.15.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user (typically an administrator) accesses a page displaying dynamic user data (such as via the Dynamic Data feature pulling user biographical information).
