GraphQL Week on The Hacker101 Capture the Flag Challenges

HackerOne announces three GraphQL-based Hacker101 Capture the Flag challenges (levels 1–3) that teach querying, mutations, and file attachment handling in GraphQL; the post highlights top solvers and notes a few publicly disclosed GraphQL-related bugs reported on the HackerOne Hacktivity page and during a Shopify event. The content is educational and aimed at improving bug-hunting and secure GraphQL implementation rather than reporting a specific active incident.
