MeshCentral stores the agent-supplied osdesc (OS description) field from the coreinfo message with no HTML sanitization, and renders it into the admin device details panel via innerHTML. A rogue or compromised MeshAgent can therefore inject arbitrary HTML and JavaScript that executes in the browser session of any administrator who views the device, and the management UI content security policy permits unsafe-inline. Fixed in 1.1.60, which wraps the value in EscapeHtml().
