Short explanation

CLI Bridge prior to version 0.0.2 contains a high-severity sandbox escape vulnerability caused by dangling symlinks bypassing resolveSafePath when fs.realpathSync throws ENOENT for a nonexistent target.

Why does it matter?

This vulnerability allows write_file to follow the link and write arbitrary files outside the workspace root.

What should be done?

  • Upgrade cli-bridge to version 0.0.2 or later
  • Follow the vendor advisory

Show the technical text from the sources

CLI Bridge provides filesystem access within a workspace root. Prior to 0.0.2, a dangling symlink pointing outside the workspace root bypasses resolveSafePath when fs.realpathSync throws ENOENT for a nonexistent target. The fallback resolves only the parent directory and returns the symlink path as safe, so write_file follows the link and can write arbitrary files outside the workspace root. This issue is fixed in version 0.0.2.
