🚨 ACTIVE INCIDENT: The Mini Shai-Hulud worm is back, and it just compromised dozens of official @tanstack npm packages This is the first documented self-spreading npm worm that carries valid SLSA provenance attestations. Let that sink in. Our OSS Package Security Feed detected the compromised releases and we're tracking the spread in real time. Here's what happened: The attacker staged an obfuscated 2.3 MB credential-stealing payload in a fork of TanStack/router, then used hijacked OIDC tokens to publish malicious versions through TanStack's own legitimate GitHub Actions release pipeline. The compromised packages include @tanstack/react-router, @tanstack/router-core, @tanstack/react-start, and 40+ other packages. Millions of weekly downloads across the ecosystem. If you installed any affected version in CI, assume all secrets in that environment are compromised. Rotate tokens immediately. Full technical analysis, IOCs, compromised version list, and recovery steps on our blog. The list of affected packages is still growing.
