Enterprises are racing to deploy AI agents that pull from databases, document repositories, and SaaS platforms to automate workflows.

Just as we discussed the catastrophic consequences of unauthorized data manipulation in our recent breakdown of the Critical GitLab GraphQL Flaw, relying on application-level filtering for AI access is a severe structural weakness.
