CVE-2024-6960 is a deserialization vulnerability in the H2O machine learning platform, allowing arbitrary code execution. Attackers can craft malicious "Iced" models containing serialized Java objects, which, upon deserialization, execute arbitrary code due to the lack of a class whitelist. This vulnerability carries a high CVSS score of 7.5, indicating a network-based attack with high impact on confidentiality, integrity, and availability, though it requires user interaction and has high attack complexity. Currently, there is no public exploit code available, it is not listed in CISA's KEV catalog, and there is no community discussion or media coverage surrounding this CVE.
