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. The vulnerability is present in the mlflow/server/auth/__init__.py file, where the user-supplied Content-Type header is directly injected into a Python formatted string and returned to the user, facilitating the XSS attack.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/mlflow/mlflow/commit/28ff3f94994941e038f2172c6484b65dc4db6ca1","https://huntr.com/bounties/816bdaaa-8153-4732-951e-b0d92fddf709","https://github.com/mlflow/mlflow/commit/28ff3f94994941e038f2172c6484b65dc4db6ca1","https://huntr.com/bounties/816bdaaa-8153-4732-951e-b0d92fddf709"],"products":["lfprojects:mlflow"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-6568","score":0.01662,"percentile":0.76703,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vwhf-3v6x-wff8","url":"https://osv.dev/vulnerability/GHSA-vwhf-3v6x-wff8","summary":"Cross-site Scripting (XSS) in MLflow","modified":"2024-04-16T19:01:12.743559Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<2.9.0"],"fixed":["2.9.0"]}]},{"id":"PYSEC-2023-260","url":"https://osv.dev/vulnerability/PYSEC-2023-260","summary":"","modified":"2026-06-10T17:02:17.395201250Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<2.9.1"],"fixed":["2.9.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
