Technical details
This vulnerability exists in Ivanti Neurons for ITSM versions before 2026.2 and involves insecure deserialization of untrusted data. The flaw allows a remote authenticated attacker to craft and send malicious serialized objects that execute arbitrary code with server privileges when deserialized. The vulnerability requires existing authentication credentials to exploit, limiting exposure to authenticated users.
