Avada < 7.11.7 - Unauthenticated Sensitive Information Exposure via Form Uploads Directory Listing

Description The Avada theme for WordPress is vulnerable to Sensitive Information Exposure via the ‘/wp-content/uploads/fusion-forms/’ directory. This makes it possible for unauthenticated attackers to extract sensitive data uploaded via an Avada created form with a file upload mechanism.

PoC

Access the URL: https://target-site.tld/wp-content/uploads/fusion-forms/ on sites running Avada with versions lower than 7.11.7 and that have directory browsing enabled on their webserver to have access to the files uploaded in there.
