Detailsinfo

A vulnerability was found in Apache Fory 0.14.0/1.3.x. It has been declared as critical. Affected by this vulnerability is an unknown code block of the component C++ implementation. The manipulation with an unknown input leads to a out-of-bounds vulnerability. The CWE definition for the vulnerability is CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Heap type confusion and out-of-bounds read/write in the Apache Fory C++ implementation. When deserializing data in compatible mode, the field-skip paths do not correctly validate the declared field types against the actual data, so input with an inconsistent schema can cause type confusion and out-of-bounds memory access. Only the C++ implementation is affected; other language implementations of Apache Fory are not. This issue affects Apache Fory C++: from 0.14.0 before 1.4.0. Users are recommended to upgrade to version 1.4.0, which fixes the issue.

The advisory is shared at lists.apache.org. This vulnerability is known as CVE-2026-64608 since 07/20/2026. The exploitation appears to be easy. The attack can be launched remotely.
