SCA: security update for mlflow (GHSA-w5xq-c4pf-ghq7)

medium Tenable Self-Hosted Container Security Plugin ID 443128

Description

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

 - In mlflow/mlflow versions up to 3.9.0, the `SearchModelVersions` REST API endpoint and the
 `mlflowSearchModelVersions` GraphQL query lack proper per-model authorization checks when basic
 authentication is enabled. This allows any authenticated user to enumerate all model versions across all
 registered models, regardless of their permission level. The issue arises due to the absence of
 `SearchModelVersions` in the `BEFORE_REQUEST_VALIDATORS` and `AFTER_REQUEST_HANDLERS` for the REST API,
 and its omission from `GraphQLAuthorizationMiddleware.PROTECTED_FIELDS` for GraphQL. This vulnerability
 can expose sensitive information such as model names, version descriptions, source URIs, tags, and other
 metadata, potentially revealing proprietary or confidential details in multi-tenant environments. The
 issue is resolved in version 3.10.0. (CVE-2026-2734)

Solution

Update the mlflow library and its related packages to version 3.10.0 or later.
