CVE-2026-71558
EUVD-2026-5442207.08.2026, 10:16
Heap type confusion vulnerability in Apache Fory C++ deserialization. This issue affects Apache Fory C++ versions from 0.14.0 before 1.5.0. A crafted input payload can bypass type compatibility checks during polymorphic smart-pointer deserialization, causing an object of an incompatible type to be treated as the declared base type. This may result in undefined behavior and potentially lead to denial of service or arbitrary code execution. Users are recommended to upgrade to Apache Fory 1.5.0, which fixes this issue. Applications not using Apache Fory C++ polymorphic smart-pointer deserialization are not affected.

Common Weakness Enumeration
- CWE-502 - Deserialization of Untrusted DataThe application deserializes untrusted data without sufficiently verifying that the resulting data will be valid.
- CWE-843 - Access of Resource Using Incompatible Type ('Type Confusion')The program allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
