CVE-2026-71560: CWE-502 Deserialization of Untrusted Data in Apache Software Foundation Apache Fory
CVE-2026-71560 is an out-of-bounds read vulnerability in Apache Fory C++ deserialization affecting versions 0.14.0 before 1.5.0. The flaw occurs when deserializing structs with tagged integer fields, potentially leading to information disclosure or denial of service. Users are advised to upgrade to version 1.5.0, which addresses this issue. Applications not using Apache Fory C++ or tagged integer fields are not impacted.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds heap read triggered during the deserialization of structs containing tagged integer fields in Apache Fory C++ versions from 0.14.0 up to but not including 1.5.0. A crafted input payload can exploit this flaw in the tagged integer fast-path deserializer, potentially causing information disclosure or denial of service. The issue is fixed in Apache Fory 1.5.0.
Potential Impact
Exploitation of this vulnerability may result in information disclosure or denial of service due to an out-of-bounds heap read during deserialization. The impact is limited to applications using Apache Fory C++ with tagged integer fields. No known exploits are reported in the wild.
Mitigation Recommendations
Users should upgrade to Apache Fory version 1.5.0, which fixes this vulnerability. Applications not using tagged integer fields or not using Apache Fory C++ are not affected and require no action.
