Description
The Avada (Fusion) Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.15.1. This is due to the plugin's `fusion_get_post_custom_field()` function failing to validate whether metadata keys are protected (underscore-prefixed). This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract protected post metadata fields that should not be publicly accessible via the Dynamic Data feature's `post_custom_field` parameter.
