CVE-2026-64608: CWE-843 Access of Resource Using Incompatible Type ('Type Confusion') in Apache Software Foundation Apache Fory
CVE-2026-64608 is a heap type confusion and out-of-bounds read/write vulnerability in the Apache Fory C++ implementation. It occurs during deserialization in compatible mode when field-skip paths fail to properly validate declared field types against actual data, leading to type confusion and memory access errors. Only the C++ implementation of Apache Fory versions from 0.14.0 before 1.4.0 is affected. Users are advised to upgrade to version 1.4.0, which addresses this issue.
AI Analysis
Technical Summary
This vulnerability in Apache Fory C++ arises from improper validation of field types during deserialization in compatible mode. Specifically, the field-skip paths do not verify that the declared field types match the actual data, resulting in heap type confusion and out-of-bounds memory read/write. This can lead to memory corruption or crashes. The issue affects versions starting at 0.14.0 up to but not including 1.4.0. Other language implementations of Apache Fory are not impacted. The recommended remediation is to upgrade to Apache Fory version 1.4.0, where the issue is fixed.
Potential Impact
The vulnerability allows an attacker to cause type confusion and out-of-bounds memory access during deserialization, potentially leading to memory corruption or application crashes. This can undermine the stability and security of applications using the affected Apache Fory C++ versions. No known exploits in the wild have been reported.
Mitigation Recommendations
Users should upgrade Apache Fory C++ to version 1.4.0 or later, which fixes the vulnerability. No other mitigation or temporary workaround is indicated. Patch status is not explicitly confirmed in the advisory, but upgrading to 1.4.0 is recommended as the fix.
