Descriptions

Missing Authorization vulnerability in ThemeFusion Avada.This issue affects Avada: from n/a through 7.11.1.

Vulnerabilidad de autorización faltante en ThemeFusion Avada. Este problema afecta a Avada: desde n/a hasta 7.11.1.

The Avada theme for WordPress is vulnerable to arbitrary file uploads due to missing file type validation when extracting zip files in the 'process_upload' and 'regenerate_icon_files' functions in versions up to, and including, 7.11.1. This makes it possible for authenticated attackers with author permissions to upload arbitrary files on the affected site's server which may make remote code execution possible.
