      "value": "4gaBoards is a boards system for realtime project management. Prior to 3.3.9, 4gaBoards allows any authenticated user to enumerate account information for every user through GET /api/users and retrieve arbitrary accounts through GET /api/users/:id. The users/index and users/show actions rely only on the default is-authenticated policy in server/config/policies.js, and server/api/controllers/users/index.js returns the result of sails.helpers.users.getMany() without requester-specific authorization or response sanitization. Responses expose email, phone, organization, name, isAdmin, ssoGoogleEmail, ssoGithubEmail, and other SSO-linked email fields, including data for administrators. This enables instance-wide user enumeration, privacy loss, and targeted phishing reconnaissance. This issue is fixed in version 3.3.9."

      "value": "4gaBoards es un sistema de tableros para la gestión de proyectos en tiempo real. Antes de la versión 3.3.9, 4gaBoards permite a cualquier usuario autenticado enumerar información de cuentas para cada usuario a través de GET /API/users y recuperar cuentas arbitrarias a través de GET /API/users/:id. Las acciones users/index y users/show se basan únicamente en la política predeterminada is-authenticated en server/config/policies.js, y server/API/controllers/users/index.js devuelve el resultado de sails.helpers.users.getMany() sin autorización específica del solicitante o sanitización de la respuesta. Las respuestas exponen email, teléfono, organización, nombre, isAdmin, ssoGoogleEmail, ssoGithubEmail y otros campos de correo electrónico vinculados a SSO, incluyendo datos para administradores. Esto permite la enumeración de usuarios a nivel de instancia, la pérdida de privacidad y el reconocimiento de phishing dirigido. Este problema está solucionado en la versión 3.3.9."
