## Overview

Salt contains an authentication protocol version downgrade weakness that can allow a malicious minion to bypass newer authentication/security features by using an older request payload format, enabling minion impersonation and circumventing protections introduced in response to prior issues.

## Affected packages

- `salt >= 3006.12, < 3006.17`
- `salt >= 3007.4, < 3007.9`

## Remediation

Upgrade to a patched release:

- `salt 3006.17`
- `salt 3007.9`
