Apache Fory fory-core Java SDK replace-resolve deserialization checks bypass
CVE-2026-50076 is a deserialization of untrusted data vulnerability in the Java replace-resolve path of Apache Fory fory-core on Java/JVM platforms. It affects org.apache.fory:fory-core versions before 1.1.0. By supplying crafted Fory serialized data, a remote attacker can bypass multiple intended deserialization safeguards, specifically class registration enforcement, TypeChecker validation, and DisallowedList checks. Successful exploitation can cause invocation of classpath-present readResolve and readExternal hooks during deserialization, creating a dangerous execution path in applications that deserialize untrusted external data using the affected library.
