CVE-2026-50076: Apache Fory Java SDK Has Deserialization of Untrusted Data in the Java replace-resolve path

June 4, 2026 (updated July 15, 2026)

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.
