Frangoteam FUXA SCADA/HMI
CISA warned that affected Frangoteam FUXA SCADA/HMI deployments can expose user and role information to unauthenticated remote attackers. The issue affects versions up to and including 1.3.1.
Why it matters: Do not expose FUXA interfaces directly to the internet; update affected systems and place ICS management services behind strong network controls.

Microsoft Warns Poisoned MCP Tool Descriptions Can Make AI Agents Leak Data
Microsoft research warns that malicious Model Context Protocol tool descriptions can influence AI agents into leaking enterprise data. The risk comes from agents trusting tool metadata while acting with user-granted permissions.
Why it matters: Treat AI tool descriptions as untrusted input, require approval for sensitive actions, and log agent decisions that involve data access or external sharing.

GuardFall Exposes Open-Source AI Coding Agents to Decades-Old Shell Injection Risks
Research on GuardFall shows that AI coding agents can still be exposed to long-known shell injection patterns despite safety checks. The findings reinforce that agent guardrails should not be treated as a substitute for secure execution design.
Why it matters: Run coding agents in sandboxed environments, restrict shell access, and use allowlisted build and test commands for automated workflows.
