Improper Access Control

Summary

A Broken Access Control vulnerability exists in mlflow versions prior to 2.12.0, where low-privilege users with only EDIT permissions on an experiment can delete any artifacts. This issue arises due to the lack of proper validation for "DELETE" requests by users with EDIT permissions, allowing them to perform unauthorized deletions of artifacts. The vulnerability specifically affects the handling of artifact deletions within the application, as demonstrated by the ability of a low-privilege user to delete a directory inside an artifact using a "DELETE" request, despite the official documentation stating that users with EDIT permission can only read and update artifacts, not delete them.
