Not news reaction. Not advisory opinion. Not consensus analysis.
Assumption Under Stress
Execution boundaries are defined by systems, not by content.
Constraint Logged
Anthropic's MCP Git Server allowed prompt injection to chain into arbitrary code execution via content an AI assistant reads. Chainlit's AI framework exposed cloud environments through file read and SSRF vulnerabilities in internet-facing deployments with no user interaction required. The binary-parser npm library permitted arbitrary JavaScript execution through data parsing. Cisco Unified Communications granted root access through web management interfaces actively exploited as zero-day before patch.
In each case, the execution surface was not the system boundary. It was the content, the data, the request.
A README file becomes a code execution vector. A custom element becomes a credential exfiltration path. A parsed buffer becomes a JavaScript interpreter. An HTTP request becomes a root shell.
What was supposed to be read is being run.
Unresolved Tension
Whether governance models that assume content is inert can survive architectures where content routinely crosses into execution.
