Source description
As published by the source; long descriptions are shortened.
In mlflow/mlflow version 2.17.2, the /graphql endpoint is vulnerable to a denial of service attack. An attacker can create large batches of queries that repeatedly request all runs from a given experiment. This can tie up all the workers allocated by MLFlow, rendering the application unable to respond to other requests. This vulnerability is due to uncontrolled resource consumption.

# Patch Next advisory brief: CVE-2025-0453 Advisory: MLflow Uncontrolled Resource Consumption vulnerability IDs: CVE-2025-0453, GHSA-49m6-vrr9-2cqm Record: https://patchnext.com/advisories/cve-2025-0453 (revision 2, source checked 26 Oct 2026, 13:35 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Medium (CVSS 5.9) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed. ## Affected components - PyPI mlflow: affected <= 2.17.2 ## Suggested inspection (read-only) - `python -m pip show mlflow`: prints the installed version. Run with the environment that serves production active. ## Supported action No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on mlflow. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://osv.dev/vulnerability/GHSA-49m6-vrr9-2cqm (OSV record GHSA-49m6-vrr9-2cqm lists affected ranges: PyPI mlflow >=0 <=2.17.2) - Verified: https://github.com/advisories/GHSA-49m6-vrr9-2cqm (GitHub-reviewed advisory GHSA-49m6-vrr9-2cqm lists affected ranges: PyPI mlflow >=0 <=2.17.2) Commands are suggestions: review each one before running it.
