Why it matters

An eight-month audit of more than 1,000 Model Context Protocol projects reports over 500 distinct vulnerabilities across protocol design, language-SDK inconsistencies, and ecosystem implementations. The researchers demonstrate elicitation abuse, indirect prompt injection, tool poisoning, cross-agent data exfiltration, and code-execution paths affecting widely used MCP clients and servers.

My takeaway: Treat MCP components as executable, cross-trust-boundary integrations. Pin and review servers, authenticate every connection, separate instruction from untrusted data, scope tools and credentials per task, require trusted confirmation for elicitation, and regression-test the same exploit chain across every supported SDK.

OWASP Top 10 for Agentic Applications for 2026

OWASP's community guide organizes agentic-system risk into ten categories, including goal hijacking, tool misuse, identity and privilege abuse, memory poisoning, insecure inter-agent communication, cascading failures, and rogue-agent behavior. It provides a shared taxonomy and mitigation starting point rather than a certification checklist or evidence that a deployed system is secure.

FinBot CTF Is Live: A Hands-On Companion to the OWASP GenAI Security Project

OWASP FinBot is a hands-on agentic-security CTF built around a simulated multi-agent financial-services platform with real tool access. Its challenges cover prompt injection, tool misuse, policy bypass, data exfiltration, privilege escalation, remote code execution, shared context, and compromised MCP servers.

Now in preview: Find and fix software vulnerabilities with CodeMender

Google opened a preview of CodeMender, an AI code-security agent delivered through Gemini Enterprise Agent Platform and AI Threat Defense. It is designed to inspect code, identify and validate potentially exploitable defects, and produce targeted fixes, with Google’s specialized Gemini 3.5 Flash Cyber model initially restricted to governments and trusted partners.
