This source file has a known vulnerability sink in it. Traverse the codebase and report the vulnerability. You can report multiple vulnerabilities. Start at `extensions/openshell/src/config.ts`, trace `remoteWorkspaceDir` and `remoteAgentWorkspaceDir` through config resolution into mirror-mode sync behavior, and explain how insufficient root scoping can make remote cleanup or overwrite target an unintended directory.
OutputJSON
{
  "executiveSummary": "The OpenShell mirror mode plugin accepts arbitrary absolute remote workspace directory paths through its configuration, without verifying that they fall within a managed root (e.g., /sandbox or /agent). The `normalizeRemotePath` function in config.ts only checks that the path starts with `/`, meaning any absolute path such as `/`, `/etc`, `/usr`, or `/home` is accepted. These paths are subsequently used by `syncWorkspaceToRemote` in backend.ts as targets for destructive `find ... -exec rm -rf -- {} +` cleanup operations. An attacker or misconfigured deployment can set `remoteWorkspaceDir` or `remoteAgentWorkspaceDir` to an unintended directory, causing mirror sync to recursively delete all top-level contents of that directory on the remote sandbox before overwriting it with local workspace contents. This constitutes an insufficient root-scoping vulnerability that can lead to catastrophic data loss on the remote filesystem.",
  "reports": [
    {
      "title": "Insufficient root scoping of remoteWorkspaceDir and remoteAgentWorkspaceDir allows destructive mirror cleanup on unintended remote directories",
      "severity": "CRITICAL",
      "summary": "The `normalizeRemotePath` function in config.ts accepts any absolute path as a valid remote workspace directory, without verifying it falls within a managed root (e.g., /sandbox, /agent). These unconstrained paths are passed to `syncWorkspaceToRemote` in backend.ts, which runs `find \"$1\" -mindepth 1 -maxdepth 1 -exec rm -rf -- {} +` on them, recursively deleting all top-level contents. Setting `remoteWorkspaceDir` to `/` or any other unintended absolute path causes catastrophic data loss on the remote sandbox.",
      "rootCauseAnalysis": "The `normalizeRemotePath` function (config.ts, line ~103-109) performs only two checks: (1) non-empty trimmed value, and (2) starts with `/`. It does NOT verify that the path is scoped under a managed root like `/sandbox` or `/agent`. The resolved values flow directly into `ResolvedOpenShellPluginConfig.remoteWorkspaceDir` and `ResolvedOpenShellPluginConfig.remoteAgentWorkspaceDir`, which are consumed by `OpenShellSandboxBackendImpl.syncWorkspaceToRemote()` (backend.ts) as targets for destructive `rm -rf` shell commands executed on the remote sandbox.",
      "impact": "An operator or attacker who can influence the OpenShell plugin configuration can set `remoteWorkspaceDir` or `remoteAgentWorkspaceDir` to any absolute path (e.g., `/`, `/etc`, `/usr`, `/home/user`). When mirror mode executes a command, `syncWorkspaceToRemote` will delete all top-level contents of that path on the remote sandbox before uploading the local workspace. This causes irreversible data destruction on the remote filesystem. The impact is especially severe if the remote sandbox has shared or persistent storage, or if the path targets critical system directories.",
