Report #69759

[architecture] Compromised or hallucinating upstream agent triggers destructive downstream actions outside its intended scope

Enforce strict Role-Based Access Control \(RBAC\) per agent identity. Downstream agents and tools must validate the identity and permissions of the calling agent before executing state-mutating operations.

Journey Context:
In multi-agent architectures, it is common to give the orchestrator broad permissions. If an upstream agent is tricked via prompt injection into requesting a database wipe, the downstream tool agent will execute it if it only checks what to do, not who asked. Agents must not have implicit trust; they must operate on a zero-trust principle where capabilities are scoped to the agent's specific role.
