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.

{
"executiveSummary": "The OpenShell extension in mirror mode accepts arbitrary absolute paths for `remoteWorkspaceDir` and `remoteAgentWorkspaceDir` configuration options without validating they are within a managed sandbox root. The config resolver (`normalizeRemotePath`) only verifies paths are absolute (start with `/`) but imposes no root scoping restrictions. When mirror mode synchronizes workspaces, it uses these paths in destructive shell commands (`find ... -exec rm -rf`) and as upload destinations. An attacker who can influence plugin configuration can point these settings to system directories (e.g., `/etc`, `/home`, `/`), causing unintended remote cleanup or data overwrite outside the intended sandbox scope.",

"title": "OpenShell Mirror Mode Path Traversal via Mis-scoped Remote Workspace Directories",
"severity": "HIGH",
"summary": "The OpenShell extension's mirror mode accepts arbitrary absolute paths for `remoteWorkspaceDir` and `remoteAgentWorkspaceDir` without validating they are within a managed sandbox root. The config resolver only checks that paths are absolute (start with `/`) but does not restrict them to a safe scope. Mirror sync operations use these paths in destructive shell commands (`rm -rf`) and as upload targets, allowing an attacker to target unintended remote directories for cleanup or overwrite.",
"rootCauseAnalysis": "In `config.ts`, the `normalizeRemotePath` function validates that configured paths are absolute but does not enforce that they fall within an allowed managed root (like `/sandbox` or `/agent`). In backend.ts, mirror mode's `syncWorkspaceToRemote()` method uses these paths directly in shell commands: `mkdir -p -- '$1' && find '$1' -mindepth 1 -maxdepth 1 -exec rm -rf -- {} +`. This cleans the target directory and uploads local contents to it. Since no validation ensures the path is within intended sandbox boundaries, arbitrary absolute paths are accepted and operated on.",
"impact": "An attacker who can control the OpenShell plugin configuration (e.g., via crafted config files or environment variables) can set `remoteWorkspaceDir` or `remoteAgentWorkspaceDir` to sensitive system directories like `/etc`, `/home`, `/var/lib`, or `/`. In mirror mode, this causes: (1) unintended cleanup (deletion) of all immediate contents of the targeted directory via `find ... rm -rf`, and (2) overwriting of the targeted directory with local workspace contents. This can lead to data loss, system compromise, or destruction of critical system files on the remote sandbox host.",
"attackPath": "1. Attacker provides malicious OpenShell plugin configuration setting `remoteWorkspaceDir` to `/etc` or other sensitive path. 2. Plugin config resolver validates the path is absolute and returns it unchanged (only normalization via `path.posix.normalize`). 3. When mirror mode activates, `syncWorkspaceToRemote()` executes shell commands that clean the remote directory: `find /eTool calls
