In versions prior to 4.4.1, when the <code>MVStoreUtils.openOrCreate()</code> method detects a legacy v1-format store or encounters a compatibility error, it triggers an automatic migration path. This path deserializes stored values by passing raw bytes to <code>java.io.ObjectInputStream.readObject()</code> via a custom <code>NitriteObjectInputStream</code> subclass. This subclass does not implement an allowlist, blocklist, or ObjectInputFilter. Consequently, any <code>Serializable</code> class reachable on the application's classpath can be instantiated, leading to the unconditional invocation of <code>readObject()</code>, <code>readExternal()</code>, or <code>readResolve()</code> callbacks. The presence of a gadget class on the classpath is a precondition for remote code execution. This issue has been patched in version 4.4.1.</p>
