ThemeFusion Products Authorization Bypass

This is a missing authorization vulnerability in ThemeFusion Avada Core (versions prior to 5.15.0) that allows unauthenticated attackers to modify data through incorrectly configured access control security levels. The vulnerability has a CVSS score of 5.3 with network attack vector and no privilege requirements, meaning any remote attacker can exploit it without authentication. While the integrity impact is limited (data modification rather than disclosure or system compromise), the lack of authentication requirements and network accessibility make this a practical security concern for websites using vulnerable Avada versions.

This vulnerability is a missing authorization flaw in ThemeFusion Fusion Builder that allows unauthenticated attackers to exploit incorrectly configured access controls to modify content or settings. The issue affects Fusion Builder versions prior to 3.15.0, and the network-accessible nature combined with no authentication requirement means any remote attacker can exploit it without special privileges. While the CVSS score of 5.3 indicates moderate severity with integrity impact but no confidentiality or availability loss, the lack of authentication requirement elevates real-world risk for WordPress sites using affected versions.
