Summary
CVE-2023-6568 is a reflected Cross-Site Scripting (XSS) flaw in the mlflow/mlflow repository, in how POST requests handle the Content-Type header. The header value is injected into a Python formatted string in mlflow/server/auth/__init__.py and returned to the user without sanitization or escaping. An attacker can therefore run arbitrary JavaScript in a victim's browser.
