pip install salt>=2016.11.10
salt fixed: 2017.7.8 
pip install salt>=2017.7.8
salt fixed: Latest secure release 
pip install salt>=Latest secure release
salt fixed: 2019.2.8

pip install salt>=3000.7
salt fixed: 3001.5 
pip install salt>=3001.5
salt fixed: 3002.3 
pip install salt>=3002.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show salt

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2021-25284, inspect your installed packages using pip:

pip show salt

Analyze the terminal output to locate any version of Salt in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2015.8.13), your application is affected.

Note: The pip show salt command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis
