By sending multiple concurrent requests to view any user profile on instances with many registered users, an authenticated attacker can easily exhaust database resources and completely deny access to the application for other users.\nBecause vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions."

Al enviar múltiples solicitudes concurrentes para ver cualquier perfil de usuario en instancias con muchos usuarios registrados, un atacante autenticado puede agotar fácilmente los recursos de la base de datos y denegar completamente el acceso a la aplicación a otros usuarios. Debido a que los intentos de contacto con el proveedor no tuvieron éxito, la vulnerabilidad solo se ha confirmado en la versión 7.7.5 pero también puede afectar a otras versiones."
