CVE-2023-6568

Summary

CVE-2023-6568 is a reflected Cross-Site Scripting (XSS) vulnerability discovered in the mlflow/mlflow repository. Specifically, the issue lies within the handling of the Content-Type header in POST requests in the mlflow/server/auth/__init__.py file. An attacker can exploit this vulnerability by injecting malicious JavaScript code into the Content-Type header, which is then unsanitized and reflected back to the user. This results in arbitrary JavaScript execution in the victim's browser, potentially leading to data theft or unauthorized access. The vulnerability arises due to direct injection of user-supplied Content-Type headers into a Python formatted string, bypassing adequate sanitization or escaping mechanisms.
