      "value": "PdfDing is a selfhosted PDF manager, viewer and editor offering a seamless user experience on multiple devices. Prior to version 1.7.0, an access-control vulnerability allows unauthenticated users to retrieve password-protected shared PDFs by directly calling the file-serving endpoint without completing the password verification flow. This results in unauthorized access to confidential documents that users expected to be protected by a shared-link password. This issue has been patched in version 1.7.0."

      "value": "PdfDing es un gestor, visor y editor de PDF autoalojado que ofrece una experiencia de usuario fluida en múltiples dispositivos. Antes de la versión 1.7.0, una vulnerabilidad de control de acceso permite a usuarios no autenticados recuperar PDF compartidos protegidos con contraseña al llamar directamente al endpoint de servicio de archivos sin completar el flujo de verificación de contraseña. Esto resulta en acceso no autorizado a documentos confidenciales que los usuarios esperaban que estuvieran protegidos por una contraseña de enlace compartido. Este problema ha sido parcheado en la versión 1.7.0."
