  "title": "Unauthenticated template injection in Larapaper screen API",
  "summary": "Larapaper versions before 0.46.0 can disclose credentials for registered devices and accept attacker-controlled server-side templates through its screen-management API. A remote attacker needs to know or predict a registered device MAC address, after which they may execute PHP with the web server's permissions.",
  "mitigation": "Upgrade Larapaper to version 0.46.0. Until upgraded, restrict access to the affected API endpoints to trusted networks; disabling Auto-Join alone does not protect already registered devices.",
