What the vulnerability does
The Avada (Fusion) Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘Module Title’ parameter in all versions up to, and including, 3.15.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Avada (Fusion) Builder versions up to 3.15.5 contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, potentially compromising their sessions or stealing data. The vulnerability affects the site's scope, meaning impacts may extend beyond the builder component itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers when they view affected pages.
Potential impact on your site
Visitors' sessions and data can be compromised by authenticated users with low privileges injecting malicious code.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site; no user interaction required.
