In Apache Ignite 2.3 or earlier, the serialization mechanism does not have a list of classes allowed for serialization/deserialization, which makes it possible to run arbitrary code when 3-rd party vulnerable classes are present in Ignite classpath. The vulnerability can be exploited if the one sends a specially prepared form of a serialized object to one of the deserialization endpoints of some Ignite components - discovery SPI, Ignite persistence, Memcached endpoint, socket steamer.

Security readout for executives and security teams

Apache Ignite 2.3 and earlier may deserialize untrusted data without an allow-list. If vulnerable third-party classes are present, specially crafted serialized data sent to certain Ignite components could lead to arbitrary code execution. Organizations running Apache Ignite 2.3 or earlier are potentially exposed, especially where named Ignite components accept network input or process serialized objects. Exposure is lower if affected endpoints are unreachable and risky third-party classes are absent. Prioritize this for environments using Apache Ignite because the impact can be code execution. Urgency depends on whether affected versions are present and whether Ignite endpoints are reachable. Mitigation focus: Inventory Apache Ignite deployments and confirm versions.; Prioritize Apache Ignite 2.3 or earlier for remediation review.; Follow Apache and Red Hat advisory guidance for applicable fixes..
