CVE-2024-4263Public exploitNetwork attack vector

Artifact deletion via reused update permission check

Published May 16, 2024 · Updated Aug 1, 2024

Broken access control in MLflow before 2.10.1 allows remote authenticated users with EDIT permission to delete experiment artifacts. The artifact-proxy DELETE route uses the update-permission validator, whose can_update check accepts EDIT, instead of requiring can_manage. Any account granted EDIT on an experiment can remove files or directories from that experiment's artifact store, causing data loss.
