What the vulnerability does
The Streamit theme for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'st_Authentication_Controller::edit_profile' function in all versions up to, and including, 4.0.1. This makes it possible for authenticated attackers, with subscriber-level and above permissions, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Streamit versions up to 4.0.1 allow authenticated users to upload files without proper validation. An attacker with low-level access can upload malicious files to the server, potentially executing code or compromising the site. The vulnerability requires valid user credentials but no additional user interaction.
What an attacker can do
