Overview

psitransfer is a Simple open source self-hosted file sharing solution

Affected versions of this package are vulnerable to Unrestricted Upload of File with Dangerous Type due to the absence of restrictions on the endpoint designed for uploading files. An attacker who receives the id of a file distribution can alter the files within this distribution by sending a PATCH request with arbitrary content. This modification allows the attacker to append malicious or phishing content to the end of the original file, impacting users who access the file distribution subsequently.
