"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.",
"summary": "Add contributor credit for discovery and reporting of deserialization vulnerability in DataChain",
"details": "This pull request adds contributor credit for the discovery, verification, and reporting of a deserialization vulnerability in the DataChain library. The vulnerability occurs in loader.py where serialized objects are read from environment variables (DATACHAIN__METASTORE and DATACHAIN__WAREHOUSE), allowing an attacker with control over these variables to execute arbitrary code.\n\nCWE Classification:",
