TanStack npm Packages Hit by Mini Shai-Hulud | Snyk

On May 11, 2026, the Mini Shai-Hulud worm compromised 84 npm package artifacts across 42 @tanstack/* packages (as well as @squawk/*, @mistralai/* packages, and others) by chaining a GitHub Actions "Pwn Request," cache poisoning, and OIDC token extraction from runner memory — producing the first npm supply chain attack with valid SLSA Build Level 3 attestations. Here's what happened, what was stolen, and what you need to do right now.
