An unauthorized party stole a GitHub token and used it to download the Grafana Labs codebase.
Key Takeaways
Attack vector was a stolen token granting access to Grafana Labs’ GitHub environment, not a direct repo breach.
The threat actor downloaded the codebase; Grafana disclosed this via a public thread starting May 17, 2026.
No further details on scope, affected repos, or customer data impact are available from the disclosure so far.
Hacker News Comment Review
One commenter joked that the grafana/grafana repo is already public, pointing to the open-source repo on GitHub – implying the stolen token likely targeted private internal repos beyond the public codebase.
