      "value": "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.\n\nThis issue affects Apache Fory C++: from 0.14.0 before 1.4.0.\n\nUsers are recommended to upgrade to version 1.4.0, which fixes the issue."

      "value": "Confusión de tipos en el heap y lectura/escritura fuera de límites en la implementación de Apache Fory en C++. Al deserializar datos en modo compatible, las rutas de omisión de campos no validan correctamente los tipos de campo declarados con respecto a los datos reales, por lo que una entrada con un esquema inconsistente puede causar confusión de tipos y acceso a memoria fuera de límites. Solo la implementación en C++ se ve afectada; otras implementaciones de Apache Fory en otros lenguajes no lo están.\n\nEste problema afecta a Apache Fory C++: desde la versión 0.14.0 hasta antes de la 1.4.0.\n\nSe recomienda a los usuarios actualizar a la versión 1.4.0, que corrige el problema."
