CVE-2023-6568 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. A reflected Cross-Site Scripting (XSS) vulnerability exists in the mlflow/mlflow repository, specifically within the handling of the Content-Type header in POST requests. An attacker can inject malicious JavaScript code into the Content-Type header, which is then improperly reflected back to the user without adequate sanitization or escaping, leading to arbitrary JavaScript execution in the context of the victim's browser. EPSS estimates a 1.65% chance of exploitation in the next 30 days.
