TanStack npm supply-chain attack spreads via Dependabot update

On May 11, 2026, a worm compromised TanStack's release pipeline, publishing 84 malicious versions of 42 packages to npm with valid provenance.

When the maintainer merged the update, the worm used his credentials to publish 110 malicious versions of his own packages. The incident affected over 160 packages ecosystem-wide, including those from Mistral, before being contained.

The Microsoft Agent Framework is advised for Azure-centric infrastructure as it merges AutoGen and Semantic Kernel. CrewAI is identified as the fastest option for prototyping multi-agent teams without production governance. The evaluation notes a migration deadline for Azure users, as Prompt Flow services will retire in April 2027.
