Apache Fory: Out-of-bounds heap read in C++ struct deserializer tagged-int fast-path

Assigner: apache
Reserved: 07.08.2026 Published: 07.08.2026 Updated: 07.08.2026

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.
