Vulnerability Description
Out-of-bounds Read vulnerability in Apache Fory C++ deserialization. This issue affects Apache Fory C++ versions from 0.14.0 before 1.5.0 when deserializing structs containing tagged integer fields. A crafted input payload may trigger an out-of-bounds heap read in the tagged integer fast-path deserializer, potentially causing information disclosure or denial of service. Users are recommended to upgrade to Apache Fory 1.5.0, which fixes this issue. Applications that do not use Apache Fory C++ or do not use tagged integer fields are not affected.
