Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

MLflow versions prior to 3.9.0 are vulnerable to server-side request forgery through webhook creation, where the webhook URL is accepted without validation. An authenticated attacker can make the MLflow backend send HTTP POST requests to internal services, cloud metadata endpoints, or external servers, potentially enabling credential theft or data exfiltration. Upgrade to MLflow 3.9.0 or later.
