Fixed In Version: keycloak 11.0.0
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in Keycloak, 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.

Description Marian Rehak 2019-05-03 10:27:21 UTC 
The Keycloak code base contains some usages of ObjectInputStream without any type checks. This could be exploited by attackers being able to inject arbitrarily serialized Java Objects which would then get deserialized in a priviliged context potentially leading to Remote Code Execution.

Comment 1 Jason Shepherd 2019-08-12 02:02:53 UTC 
Red Hat Mobile application platform (RHMAP) does not make use of the Keycloak Kerberos 5 Delegated Authorization feature, which does the unsafe deserialization. The other usage of ObjectInputStream pointed out in KEYCLOAK-10162 is used for reading the KeycloakSecurityContext out of the HTTP cache in the application server, which doesn't pose a threat to RHMAP because it's not accepting user input to be deserialized.
