## Resource

This story was originally published on HackerNoon at: https://hackernoon.com/prompt-injection-is-now-an-rce-primitive . When AI controls tools, prompt injection becomes execution risk. Map primitives, remove authority, isolate runtimes, validate inputs, and monitor hosts. Check more stories related to cybersecurity at: https://hackernoon.com/c/cybersecurity .

The article argues that prompt injection in tool-using agents should be treated as an execution-path problem, not just a content-filtering problem. Its core recommendation is to map every untrusted input source to the tools, primitives, credentials, filesystem paths, and network destinations it can reach, then break those paths with least privilege, typed tool design, sandboxing, scoped credentials, approval gates, and host-level monitoring.
