  "title": "Arbitrary code execution in MLflow third-party scorer loading",
  "summary": "MLflow versions from 3.12.0rc0 through versions before 3.17.0 can load unintended modules when processing third-party scorers. An attacker able to place code in a server-writable allowed scorer package can cause code execution; this is unauthenticated when authentication is disabled, while basic-auth deployments require relevant artifact upload permissions.",
  "mitigation": "Upgrade MLflow to version 3.17.0. Until upgraded, restrict scorer invocation and ensure allowed third-party scorer package locations are not writable by the MLflow server process.",
