The OWASP Top 10 for Agentic Applications defines the most critical security risks for autonomous AI agents in 2026. From prompt injection and tool hijacking to supply chain poisoning and multi-agent attacks, this comprehensive guide covers every vulnerability with real attack scenarios and proven defense strategies.
One week in April 2026 delivered a CVSS 9.8 AI-agent flaw, an unauthenticated SGLang RCE, MCP memory poisoning, and a 766-host credential harvest. Here's the full analysis and your patching order.
