Description
CVE-2026-64678 is a critical deserialization vulnerability in nitrite-java versions prior to 4.4.1. The vulnerability arises from unsafe deserialization of legacy database files without any class allowlist or filtering, allowing arbitrary classes on the application classpath to be instantiated during deserialization. This can enable remote code execution if a suitable gadget class is present. The issue is fixed in version 4.4.1.
