Out-of-bounds Read in Apache Fory C++

Publication date: 2026-08-07

Last updated on: 2026-08-07

Assigner: Apache Software Foundation

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.

Executive Summary

This is an out-of-bounds read vulnerability in Apache Fory C++ affecting versions 0.14.0 to before 1.5.0 during deserialization of structs with tagged integer fields. A specially crafted input may cause a heap read outside allocated memory, potentially leading to information disclosure or denial of service.

Detection Guidance

Detection involves checking Apache Fory C++ versions and monitoring for crashes or memory corruption during deserialization of tagged integer fields. No specific commands are provided in the context.

Impact Analysis

The vulnerability may allow attackers to read sensitive memory contents or crash the application, causing denial of service. Systems processing untrusted serialized data with tagged integers are at risk.

Compliance Impact

This vulnerability may lead to information disclosure, which could violate data protection requirements under GDPR or HIPAA if sensitive data is exposed. Denial of service risks could also impact service availability, potentially breaching compliance for regulated systems.

Mitigation Strategies

Upgrade Apache Fory C++ to version 1.5.0 or later. If the application does not use Apache Fory C++ or tagged integer fields, no action is required.
