This means that an attacker getting access to a remember-me token for one server can get access to all servers which allow log-in using the same credentials without ever needing the credentials. This problem is fixed in Opencast 7.6 and Opencast 8.1"

Esto significa que un atacante que obtiene acceso a un token remember-me para un servidor puede obtener acceso a todos los servidores que permiten el inicio de sesi\u00f3n con las mismas credenciales sin necesidad alguna de las credenciales.
