Authenticated availability loss via REST deserialization

Published Aug 31, 2022 · Updated Aug 3, 2024

Deserialization of untrusted data in Apache Geode before 1.15.0 allows remote authenticated users to interrupt service through its REST API. The published advisory identifies the REST API as the deserialization path but does not disclose the affected class, method, or input-handling operation. The flaw is reachable only when Developer REST is enabled on Java 8 or Java 11; the reported impact is availability loss without data disclosure or modification.
