Avada vulnerabilities

The Avada theme for WordPress up to version 7.16 is vulnerable to Arbitrary File Write when the Fusion Builder plugin is installed and active in versions up to 3.16. A chain of authorization and input validation weaknesses allows unauthenticated attackers to write attacker-controlled files to the server, leading to remote code execution and complete site compromise. Successful exploitation requires both Avada and Fusion Builder installed and active, as well as certain administrator-authored content.

Avada versions up to 3.15.3 are vulnerable to PHP Object Injection, potentially allowing unauthorized access to the system.

Cross-Site Request Forgery (CSRF) vulnerability in ThemeFusion Avada theme. Allows an attacker to perform unauthorized actions on behalf of a logged-in administrator. Affects versions before 7.13.2.
