CVE-2026-50076: CWE-502 Deserialization of Untrusted Data in Apache Software Foundation Apache Fory
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.
AI Analysis
Technical Summary
This vulnerability involves unsafe deserialization of untrusted data in the Java replace-resolve path within Apache Fory's fory-core Java SDK prior to version 1.1.0. An attacker can craft serialized data that bypasses class registration, TypeChecker, and DisallowedList security mechanisms, allowing invocation of readResolve or readExternal hooks present in the classpath. This could lead to unintended code execution or other impacts related to deserialization flaws. The vendor recommends upgrading to version 1.1.0 or later to remediate this issue.
Potential Impact
The vulnerability allows remote attackers to bypass critical deserialization security checks, potentially enabling execution of malicious code or manipulation of application behavior through crafted serialized data. The exact impact depends on the context in which the vulnerable SDK is used, but it represents a significant security risk inherent to deserialization of untrusted data.
Mitigation Recommendations
Users should upgrade Apache Fory to version 1.1.0 or later, where this vulnerability is fixed. No other mitigation guidance is provided. Patch status is not explicitly confirmed in the advisory, but the vendor recommendation to upgrade indicates an official fix is available in version 1.1.0.
