🚨 AI SECURITY PULSE

Hello!

Welcome to Secure Prompt's weekly newsletter, issue #14.

This week marks a watershed moment for AI infrastructure security. A critical RCE vulnerability in vLLM (CVE-2026-22778) exposed millions of AI servers to takeover via malicious video URLs, while Sysdig documented threat actors using LLMs to breach AWS environments in just 8 minutes. Meanwhile, OpenAI admitted that prompt injection in browser agents is effectively "unfixable," forcing a fundamental rethink of agentic AI security architectures.

The convergence of these events signals a harsh reality: the AI security tools we've deployed are being outpaced by adversaries who understand LLM infrastructure better than many defenders. Organizations must shift from experimental AI deployments to production-grade security frameworks—or accept the inevitability of compromise.
