Welcart e-Commerce < 2.9.5 - Cross-Site Request Forgery

Description

The plugin is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.9.4. This is due to missing or incorrect nonce validation on several functions. This makes it possible for unauthenticated attackers to upload files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Since uploaded files were not verified properly, this could lead to arbitrary file upload.
