https://notcve.org/view.php?id=CVE-2020-1714
A flaw was found in Keycloak before version 11.0.0, where the code base contains usages of ObjectInputStream without type checks. This flaw allows an attacker to inject arbitrarily serialized Java Objects, which would then get deserialized in a privileged context and potentially lead to remote code execution. Se detectó un fallo en Keycloak versiones anteriores a 11.0.0, donde la base de código contiene usos de la función ObjectInputStream sin ningún tipo de comprobaciones. Este fallo permite a un atacante inyectar Objetos Java serializados arbitrariamente, que luego se deserializarán en un contexto privilegiado y conlleva potencialmente a una ejecución de código remota.
