Meta Releases AgentKits with 60 Production-Ready Agent Blueprints

FIRST LOOK ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 7.2 Meta AI (via HN)

AgentKits ships 60 open, free AI agent blueprints covering 30 operational categories — from incident response and access provisioning to HR screening and fraud detection — complete with copyable system prompts, tool definitions, and workflow architectures targeting Claude, OpenAI, LangGraph, and n8n. The free, no-login distribution model dramatically lowers the barrier for adversaries to study, clone, or weaponise production-grade agent architectures, including sensitive categories like SecOps triage, access provisioning, and compliance monitoring. Defenders must treat these blueprints as publicly documented attack playbooks and audit any internally deployed instances against their documented worst-case actions and trust levels.

CVE-2025-67644: LangGraph SQLi to RCE via Checkpointer

CVE-2025-67644: LangGraph SQLi to RCE via Checkpointer

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.2 Check Point Research

Check Point Research disclosed three vulnerabilities in LangGraph's persistence layer, two of which chain together to achieve remote code execution: a SQL injection flaw in the SQLite checkpointer (CVE-2025-67644) and an unsafe msgpack deserialization bug (CVE-2026-28277). A third parallel injection vulnerability (CVE-2026-27022) affects the Redis checkpointer. With over 50 million monthly downloads, self-hosted LangGraph deployments exposing user-controlled state history filters are directly at risk.

CVE-2026-26030: Semantic Kernel RCE via Prompt Injection

CVE-2026-26030: Semantic Kernel RCE via Prompt Injection

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.2 Microsoft Security Blog

Microsoft's Defender Security Research Team disclosed two CVEs in Semantic Kernel — a widely-used AI agent orchestration framework — demonstrating how prompt injection can escalate to remote code execution via compromised plugins. The vulnerabilities (CVE-2026-26030 and CVE-2026-25592) expose a systemic risk in the agentic AI layer: because frameworks like Semantic Kernel abstract tool orchestration, a single flaw in how LLM outputs are mapped to system tools can propagate across every application built on that foundation. This research signals a critical shift in AI threat modelling, where prompt injection is no longer a content risk but an execution risk.

CVE-2026: Anthropic MCP SDK Remote Code Execution

CVE-2026: Anthropic MCP SDK Remote Code Execution

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.4 The Hacker News

A systemic 'by design' vulnerability in Anthropic's Model Context Protocol (MCP) SDK enables arbitrary remote code execution across all supported language implementations via unsafe STDIO transport defaults, affecting over 7,000 publicly accessible servers and 150 million downloads. The flaw has been independently confirmed across 10+ popular AI frameworks including LiteLLM, LangChain, and Flowise, with Anthropic declining to modify the protocol's architecture. This represents a significant AI supply chain risk with cascading exposure to sensitive data, API keys, and internal systems.
