The Avada theme for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'ajax_import_options' function in versions up to, and including, 7.11.1. This makes it possible for authenticated attackers with contributor permissions to upload arbitrary files on the affected site's server which may make remote code execution possible if they are able to successfully exploit a race condition.
Not sure which version you run? Run a passive check — it reads public files only.
Remediation & mitigations
- Update to version 7.11.2, or a newer patched version
- Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
