Problem
Severity:
High| File:experiments/logic/src/run-in-vm.ts:L12The
prepareToRunInVMfunction inrun-in-vm.tsuses Node.jsvmmodule'screateContextwith an empty object andSourceTextModuleto execute dynamically generated code. While it blocks dynamic imports via the linker, the context is not fully sandboxed - the code can still access the global object and potentially escape the VM context. This is used to execute AI-generated code inrun-test.tswhich compounds the risk since the code origin is untrusted (AI-generated).Solution
Consider using a proper sandbox like
vm2(with caveats) or better yet, isolate the execution in a separate process with restricted permissions. At minimum, freeze the context prototype chain and explicitly deny access torequire,process, and other dangerous globals. Consider usingisolated-vmpackage for proper V8 isolates.Changes
