Vulnerability from github – Published: 2026-06-04 18:30 – Updated: 2026-06-04 18:30

Details

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.

Severity

9.1 (Critical)
