summary: DataChain Vulnerable to Deserialization of Untrusted Data from Environment Variables
details: The DataChain library reads serialized objects from environment variables (such as `DATACHAIN__METASTORE` and `DATACHAIN__WAREHOUSE`) in the `loader.py` module. An attacker with the ability to set these environment variables can trigger code execution when the application loads.
