Critical GitHub Attack – Source: www.schneier.com

This is serious:

A sophisticated cascading supply chain attack has compromised multiple GitHub Actions, exposing critical CI/CD secrets across tens of thousands of repositories. The attack, which originally targeted the widely used “tj-actions/changed-files” utility, is now believed to have originated from an earlier breach of the “reviewdog/action-setup@v1” GitHub Action, according to a report.

CISA confirmed the vulnerability has been patched in version 46.0.1.

Given that the utility is used by more than 23,000 GitHub repositories, the scale of potential impact has raised significant alarm throughout the developer community.
