Elon Musk promoted Grok Build on July 18 without disclosing that the tool had uploaded entire Git repositories, commit histories, and unredacted secrets like .env files to xAI storage without user consent — a vulnerability discovered and publicly reported just two days earlier on July 16.

This post frames the product as ready to use while the security incident was still unfolding.
