CVE-2026-64608 is a memory-safety vulnerability in the Apache Fory C++ implementation affecting versions 0.14.0 through before 1.4.0. The flaw occurs during deserialization in compatible mode, where field-skip code paths do not correctly validate declared field types against the actual serialized data. A crafted input containing an inconsistent schema can therefore trigger heap type confusion and subsequent out-of-bounds memory access, including both read and write conditions. The issue is limited to the C++ implementation of Apache Fory; other language implementations are not affected.
