VectorAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Heap type confusion and out-of-bounds read/write in the Apache Fory C++ implementation. When deserializing data in compatible mode, the field-skip paths do not correctly validate the declared field types against the actual data, so input with an inconsistent schema can cause type confusion and out-of-bounds memory access. Only the C++ implementation is affected; other language implementations of Apache Fory are not.
This issue affects Apache Fory C++: from 0.14.0 before 1.4.0.
Users are recommended to upgrade to version 1.4.0, which fixes the issue.
