Publication date: 2026-06-04

Last updated on: 2026-06-08

Assigner: Apache Software Foundation

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.

Executive Summary

This vulnerability involves deserialization of untrusted data in the Java replace-resolve path within the Apache Fory fory-core Java SDK versions before 1.1.0. It allows a remote attacker to bypass important security checks such as class registration, TypeChecker, and DisallowedList. By exploiting this, the attacker can invoke certain Java hooks like readResolve or readExternal that are present in the classpath using specially crafted serialized data.

Compliance Impact

The provided information does not specify how the CVE-2026-50076 vulnerability impacts compliance with common standards and regulations such as GDPR or HIPAA.

Impact Analysis

The vulnerability can allow a remote attacker to execute unauthorized code or manipulate the deserialization process by bypassing security checks. This can lead to potential remote code execution or other malicious behaviors within applications using the affected Apache Fory fory-core Java SDK versions prior to 1.1.0.

Mitigation Strategies

Users are recommended to upgrade to version 1.1.0 or later of the Apache Fory fory-core Java SDK, which fixes this issue.
