FKIE_CVE-2026-50076

Vulnerability from fkie_nvd - Published: 2026-06-04 17:16 - Updated: 2026-07-22 20:10
Severity
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Summary
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.
