H Directory Traversal salt is a new approach to infrastructure management built on a dynamic communication bus. Salt can be used for data-driven orchestration, remote execution for any infrastructure, configuration management for any app stack, and much more. Affected versions of this package are vulnerable to Directory Traversal via the `serve_file` method, due to insufficient checks in the `salt/fileserver/roots.py` file. How to fix Directory Traversal? Upgrade `salt` to version 3005.5 or higher.	[,3005.5)
H Directory Traversal salt is a new approach to infrastructure management built on a dynamic communication bus. Salt can be used for data-driven orchestration, remote execution for any infrastructure, configuration management for any app stack, and much more.

M Improper Access Control salt is a new approach to infrastructure management built on a dynamic communication bus. Salt can be used for data-driven orchestration, remote execution for any infrastructure, configuration management for any app stack, and much more. Affected versions of this package are vulnerable to Improper Access Control. The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH.

M Information Exposure salt is a new approach to infrastructure management built on a dynamic communication bus. Salt can be used for data-driven orchestration, remote execution for any infrastructure, configuration management for any app stack, and much more. Affected versions of this package are vulnerable to Information Exposure and other possible impacts, due to a hash collision when using Git Providers reading from different environments. If Git Providers read from the wrong environment because they get the same cache directory base name, they could get bad data or unintended data. This could also lead to wrongful executions, data corruption or a crash. How to fix Information Exposure? Upgrade `salt` to version 3005.2, 3006.2 or higher.	[,3005.2)[3006.0rc1,3006.2)
