Description
Deserialization of Untrusted Data in the Java replace-resolve path in Apache Fory fory-core Java SDK before 1.1.0 on Java/JVM platforms allows a remote attacker to bypass class registration, TypeChecker, and DisallowedList checks and invoke classpath-present readResolve/readExternal hooks via crafted Fory serialized data.

Users are recommended to upgrade to version 1.1.0 or later, which fixes this issue.
