Why it matters
Over-privileged AI agents that treat untrusted document or email content as commands enable indirect prompt injection to trigger destructive or data-exfiltrating actions, as demonstrated by EchoLeak in Microsoft 365 Copilot.
An explainer on the 'permission problem' argues that most AI agents receive broader access than their tasks require, mapping the issue to OWASP's 2025 LLM Top 10 'Excessive Agency' category and citing the EchoLeak zero-click indirect prompt injection (CVE-2025-32711) in Microsoft 365 Copilot as a real-world example. Recommended mitigations include separating reasoning from execution, using short-lived scoped tokens, and sandboxing code/file interactions.
