WHY IT NEEDS A POLICY

Why postmediaimport needs a policy

This tool fetches a file from a URL and imports it into the system, creating new media content. This is a Write operation (creating new data) rather than Execute or Destructive. The severity is medium because it could be used to import malicious or unauthorized content into the digital signage infrastructure.
