AI Security Risks in 2026

**Executive summary:** This whitepaper outlines the top AI security risks for 2026—uncontrolled data exposure, Shadow AI embedded in SaaS, OAuth token abuse and over-permissioning, non-human identity sprawl, prompt injection, and AI supply-chain risk—and recommends that security teams shift from model-centric defenses to identity- and access-centric governance, including inventorying non-human identities, auditing OAuth permissions, monitoring AI usage within SaaS, and enforcing least privilege.
