A Server-Side Request Forgery (SSRF) vulnerability exists in MLflow versions prior to 3.9.0. The
_create_webhook()function inmlflow/server/handlers.pyaccepts a user-controlledurlparameter without validation, and the_send_webhook_request()function inmlflow/webhooks/delivery.pysends HTTP POST requests to this attacker-controlled URL. This allows an authenticated attacker to force the MLflow backend to send HTTP requests to internal services, cloud metadata endpoints, or arbitrary external servers. The lack of input sanitization, URL scheme filtering, or allowlist validation on the webhook URL enables exploitation, potentially leading to cloud credential theft, internal network access, and data exfiltration. - References
