GitHub action tj-actions/changed-files is compromised (no impact on Dash0)

Resolved - The widely used GitHub action, tj-actions/changed-files, experienced a security compromise. Dash0 utilized this action within our GitHub actions. Following a thorough investigation, we have confirmed that while Dash0 employed the compromised action, no evidence of token misuse was identified.

Our implementation of tj-actions/changed-files utilized ephemeral access tokens, restricted to a single repository, and valid only for the duration of individual job executions. We conducted a comprehensive audit of all relevant repository artifacts, including commits, tags, issues, pull requests, releases, and container images published via ghcr.io, to ascertain the absence of any unauthorized or malicious activity.

Dash0 maintains robust security measures, including automated systems that monitor user activity for anomalous behavior. We have taken immediate steps to ensure that similar attack patterns do not affect us going forward for our most important repositories. Furthermore, we are actively refining our security protocols to address the evolving landscape of cyber threats, with a particular focus on the secure integration of GitHub actions.

We strongly advise all GitHub action users to conduct a diligent review of their workflows for potential vulnerabilities associated with this incident. For detailed information, please see:
