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.

Successful exploitation requires both Avada and Fusion Builder installed and active, as well as certain administrator-authored content.

These fields are emitted in an anchor href without rejecting dangerous URL schemes such as javascript:.

The Avada theme for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'lang' parameter in all versions up to and including 7.16.1 due to insufficient input sanitization and output escaping.
