SCA: security update for mlflow (GHSA-65h7-c7c4-mghx)

high Tenable Self-Hosted Container Security Plugin ID 442091

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- A Server-Side Request Forgery (SSRF) vulnerability exists in MLflow versions prior to 3.9.0. The
`_create_webhook()` function in `mlflow/server/handlers.py` accepts a user-controlled `url` parameter
without validation, and the `_send_webhook_request()` function in `mlflow/webhooks/delivery.py` sends 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. (CVE-2026-2393)

Solution

Update the mlflow library and its related packages to version 3.9.0 or later.
