CVE-2026-1543

medium

Description

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).
