PyPI Supply Chain Attack Compromises elementary-data

·2026.04.28 13:54

Key point

A GitHub Actions vulnerability allowed malicious PyPI releases of elementary-data to be distributed.

Details

elementary-data was exposed to a compromised PyPI release via a GitHub Actions vulnerability.

The malicious version used a .pth file to auto-execute at Python startup, allowing the code to run without a separate import.

Environments at greater risk included the following:

  • Deployment environments that did not pin dependencies
  • Pipelines that automatically track latest

As data pipelines serve as the input path for ML systems, this incident once again revealed the vulnerability of the MLOps supply chain.
