AI Security Gaps: How Attackers Exploit Trust Boundaries

Recent attacks show that enterprise AI tools share a common weakness: they accept external input without proper security boundaries.

In June, security researchers found serious flaws in four popular AI tools. Microsoft 365 Copilot, LiteLLM, Langflow, and a supply-chain attack called Mini Shai-Hulud all had the same problem. They accepted external input without a trust boundary. This means attackers could send instructions directly to the AI system.

The Copilot flaw, called SearchLeak, let attackers steal emails from a victim's mailbox. The victim only needed to click a link. LiteLLM had a chain of three bugs that let a low-privilege user become an admin and run code remotely. Langflow had a path traversal bug that gave attackers full control. The Mini Shai-Hulud worm infected npm packages and stole credentials.

Security experts say these attacks are not about zero-day exploits. They are about poor configuration and missing security controls. Many companies deploy AI tools without proper governance. They give these tools access to sensitive data and systems. The fix is to audit AI tools, apply patches, and enforce least-privilege access. Companies must treat AI systems as untrusted until proven secure.
