What is CVE-2025-61677?

CVE-2025-61677 is a denial of service vulnerability affecting DataChain, an AI data warehouse software developed by Iterative. DataChain is designed to transform and analyze unstructured data using a Python-based architecture, facilitating efficient data handling and integration. The vulnerability arises from improper handling of serialized data, specifically through the reading of environment variables like DATACHAIN__METASTORE and DATACHAIN__WAREHOUSE within the loader.py module. This flaw allows an attacker to exploit the deserialization of untrusted data, leading to potential remote code execution when the application loads these variables. By manipulating environment settings, a malicious actor could impair DataChain's operation, severely disrupting data processing and analysis for organizations relying on this software version 0.34.1 or below. The issue has been addressed in a subsequent release, version 0.34.2.

Potential impact of CVE-2025-61677

Denial of Service: The primary impact of this vulnerability is the potential for denial of service, wherein attackers can disrupt the normal operations of DataChain, leaving organizations unable to process or analyze their data effectively.
Remote Code Execution: By exploiting this flaw, attackers could execute arbitrary code within the environment executing DataChain. This could lead to further system compromises or manipulation of data, enhancing the risks to sensitive information.
Data Integrity Threats: With the ability to execute code through this vulnerability, attackers may alter, delete, or corrupt data within the DataChain platform, leading to significant integrity issues that could undermine trust in the data analytics processes essential for decision-making within organizations.
