      "value": "ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the public API login endpoint (/api/public/user/login) returns distinguishable HTTP response codes based on whether a username exists: 404 for non-existent users and 401 for valid users with incorrect passwords. An unauthenticated attacker can exploit this difference to enumerate valid usernames, with no rate limiting or account lockout to impede the process. This issue has been fixed in version 7.2.0."

      "value": "ChurchCRM es un sistema de gestión de iglesias de código abierto. En versiones anteriores a la 7.2.0, el endpoint de inicio de sesión de la API pública (/api/public/user/login) devuelve códigos de respuesta HTTP distinguibles según si un nombre de usuario existe: 404 para usuarios inexistentes y 401 para usuarios válidos con contraseñas incorrectas. Un atacante no autenticado puede explotar esta diferencia para enumerar nombres de usuario válidos, sin limitación de velocidad (rate limiting) ni bloqueo de cuenta (account lockout) que impidan el proceso. Este problema ha sido solucionado en la versión 7.2.0."
