SCA: security update for mlflow (GHSA-wqmh-qccw-pqwf)

high Tenable Cloud Security Plugin ID 477274

Description

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

 - MLflow 3.17.1 and earlier contains a path traversal vulnerability in the FileStore tracking backend that
 allows unauthenticated attackers to control filesystem paths by submitting a crafted trace ID containing
 traversal sequences to the POST /api/3.0/mlflow/traces endpoint. Attackers can exploit
 FileStore.start_trace() to write trace_info.yaml, request_metadata, and tag files with attacker-controlled
 metadata outside the intended experiment trace directory, subject to the server process's filesystem
 permissions. FileStore is the default tracking backend before MLflow 3.7.0 and opt-in thereafter (the
 default changed to a SQLite database), so deployments in the earlier part of the affected range are
 vulnerable without special configuration while later ones are affected only when FileStore is explicitly
 selected. (CVE-2026-53995)

Solution

Update the mlflow library and its related packages to version 3.17.2 or later.
