Use a transport the guest agent actually listens on
MicroVM initialization now blocks on a vsock connection to port 5000, but the rootfs init script only launches guest_agent.py on the serial console (scripts/setup-rootfs.sh lines 33–53) and never opens a vsock listener. That means waitForAgent() will always time out once a MicroVM image is built with the provided scripts, so the runtime can’t initialize when resources are present. Either start a vsock server in the guest or switch the host-side handshake to the serial console protocol the guest uses.

Preserve quoting/args when sending commands to the guest
The MicroVM execution payload uses command.split(' '), which drops quoting and ignores any ExecutionOptions.args. Commands with spaces or shell syntax (e.g., echo "hello world", redirects, pipes) will be broken in the MicroVM runtime even though they work in the local/container runtimes that run through a shell. Consider sending ['/bin/sh','-c',command] or a proper parser that respects quoting and options.args.

In general, the correct fix is to avoid constructing a single shell command string that is interpreted by a shell. Instead, call execFile / spawn / spawnSync with the executable name and an array of arguments. This way, each argument (including paths from process.cwd() or other environment-derived values) is passed directly to the executable without shell parsing, eliminating command injection and quoting issues.
For this specific code, we should:
- Replace the
execSyncinvocation ininitializethat uses a backtickeddocker run ...command with anexecFileSynccall. - Build the Docker arguments as an array:
['run', '-d', '--rm', '--init', '-v',${this.workspacePath}:${this.workspacePath}, '--entrypoint', 'tail', this.imageName, '-f', '/dev/null']. - Remove the intermediate
mountFlagstring, which only exists for shell string concatenation. - Keep the existing
execSync('docker info', ...)andexecSync('docker rm -f ...')calls unchanged, since the CodeQL issue specifically targets the path-based mount; if desired in future, those could also be migrated, but we will not change behavior beyond the flagged snippet.
All edits are confined to packages/cli/src/runtime/ContainerRuntimeContext.ts, within the shown snippet. We will:
- Add a dynamic import of
execFileSyncfromnode:child_processinsideinitialize(alongside the existingexecSyncimport). - Change the block that computes
mountFlagand callsexecSync(...)to instead directly callexecFileSync('docker', args, { encoding: 'utf-8' })and trim the output.
