Intel Summary
Ars Technica reports that trust gaps in the Model Context Protocol (MCP) allow malicious prompt injection attacks to spread across agent-to-agent communications, affecting systems from Google and other developers.
Why It Matters
Inter-agent communication protocols without strict trust boundaries risk cascading prompt injection vulnerabilities across autonomous systems, requiring security teams and AI developers to implement isolation controls.
