📝 WalkthroughWalkthroughThe change moves default MLflow tracking from the filesystem store to SQLite. It adds artifact-location handling, SQLite engine cleanup, and a public cross-platform SQLite URI helper. MLflow tests and integration tests now use SQLite database files. Dependency constraints raise MLflow and Transformers minimum versions, pin setuptools, and constrain filelock. TransCheX now uses Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to The change is merge-ready after normal checks; one localized test cleanup issue leaves temporary directories behind, with no expected production impact, and can be fixed or followed up separately. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

It does not mention the related SQLite migration, but it clearly describes the primary dependency changes. Full details: Description checkExplanation The description explains the dependency updates, compatibility changes, SQLite migration, tests, and remaining verification work. It omits the template checkbox section, but the required change details are otherwise substantially complete. ✨ Finishing Touches🧪 Generate unit tests (beta)

- mlflow: bump floor to >=3.14.0, closing CVEs across the 2.x/early-3.x line. mlflow>=3.13 hard-errors on the local file-store backend (Project-MONAI#8891); rather than opting back into the file store, MLFlowHandler now defaults to a local SQLite backend: when no tracking_uri is given and MLFLOW_TRACKING_URI is unset it uses sqlite:///<cwd>/mlruns.db with artifacts under <cwd>/mlruns. Adds monai.utils.path_to_sqlite_uri and an artifact_location argument, updates the bundle defaults, and releases the SQLite engine on close. - transformers: bump floor to >=5.5.0, closing two HIGH severity CVEs. MultiModal now builds a real transformers.BertConfig with _attn_implementation="eager" for transformers>=4.48's attention dispatch. - setuptools: bump the build-system floor to >=78.1.1, closing one HIGH severity CVE. The old <=79.0.1 cap (Project-MONAI#8439) is no longer needed since the legacy fetch_build_eggs CLI usage is gone from setup.py. The torch.float8_e8m0fnu NGC-image concern behind the old transformers<5.0 cap should be re-verified against the current NGC base image before merging. Signed-off-by: R.

mlflow>=3.14 eagerly resolves the tracking store on MlflowClient construction and rejects the filesystem (file store) backend, so passing an explicit file:// tracking_uri now raises instead of being preserved. Remove that test; explicit-URI passthrough is still covered by the remote and SQLite tests. Also make tearDown remove SQLite db files (not just directories), fixing NotADirectoryError on Windows when the SQLite default backend creates a db file instead of a directory. Signed-off-by: R.

Summary
Closes the open Dependabot alerts for
mlflow,transformers, andsetuptools, and migrates MONAI's MLflow integration off the deprecated filesystem (file store) backend onto the recommended SQLite backend.Fixed
mlflow>=3.15.2, closing the 2.x/early-3.x CVEs and the unauthenticated webhook SSRF (CVE-2026-64849, fixed in 3.15.0). Since mlflow>=3.13 hard-errors on the filesystem tracking backend,MLFlowHandlernow defaults to a local SQLite backend (sqlite:///<cwd>/mlruns.db, artifacts under<cwd>/mlruns) and rejects explicit local-path /file://tracking URIs with an actionable error. Addsmonai.utils.path_to_sqlite_uri, anartifact_locationargument, and SQLite engine disposal onclose().transformers>=5.5.0, closing two HIGH severity CVEs.MultiModalnow builds a realtransformers.BertConfigwith_attn_implementation="eager"for transformers>=4.48's attention dispatch.setuptools>=78.1.1, closing one HIGH severity CVE. The old<=79.0.1cap (#8439) is no longer needed since the legacyfetch_build_eggsCLI usage is gone fromsetup.py.This PR supersedes #8894 (the standalone SQLite migration), which I have proposed closing.
