Report #30748
[architecture] Insecure output handling allowing agent-generated code to execute with excessive privileges
Sandbox all agent outputs in capability-restricted environments: use gVisor or Firecracker microVMs for code execution, enforce read-only database contexts with row-level security, and require cryptographic attestation for write operations
Journey Context:
Agents generating SQL, shell commands, or Python code can be hijacked via prompt injection to exfiltrate data or destroy systems. Treating agent outputs as 'trusted code' with full system access is catastrophic. Defense in depth requires: \(1\) Capability-based sandboxing using gVisor \(seccomp-bpf\) or Firecracker microVMs to restrict syscalls, \(2\) Database contexts with read-only credentials and row-level security preventing cross-tenant data access, \(3\) Approval gates for write operations requiring human or secondary agent attestation. This eliminates the 'confused deputy' problem where agents with legitimate access are tricked into misusing privileges.
