      "value": "Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. Prior to 2.2.5, the GET /api/v1/ddns and GET /api/v1/notification endpoints return full resource objects including plaintext third-party API credentials, including Cloudflare API tokens, TencentCloud SecretKeys, Slack, Discord, and Telegram webhook URLs with embedded bot tokens, and Authorization header values, without any field-level redaction. Any authenticated admin or PAT with nezha:ddns:read or nezha:notification:read scope can receive stored credentials through the listDDNS and listNotification handlers in a single API response. This issue is fixed in version 2.2.5."

Antes de la versión 2.2.5, los endpoints GET /api/v1/ddns y GET /api/v1/notification devuelven objetos de recurso completos, incluyendo credenciales de API de terceros en texto plano, como tokens de API de Cloudflare, SecretKeys de TencentCloud, URLs de webhook de Slack, Discord y Telegram con tokens de bot incrustados, y valores de encabezado de autorización, sin ninguna redacción a nivel de campo. Cualquier administrador autenticado o PAT con el alcance nezha:ddns:read o nezha:notification:read puede recibir credenciales almacenadas a través de los manejadores listDDNS y listNotification en una única respuesta de API. Este problema está solucionado en la versión 2.2.5."
