Deserialization of Untrusted Data in Hazelcast

In Hazelcast before 3.11, the cluster join procedure is vulnerable to remote code execution via Java deserialization. If an attacker can reach a listening Hazelcast instance with a crafted JoinRequest, and vulnerable classes exist in the classpath, the attacker can run arbitrary code...

Remote Code Execution Through Deserialisation

hazelcast is susceptible to remote code execution through deserialization. An attacker can send a malicious JoinRequest through which it reaches a listening Hazelcast instance if the vulnerable class is in the classpath, subsequently causing deserialization and remote code execution...
