CVE-2026-112081

A vulnerability was determined in hankcs HanLP up to 2.1.0-beta.64. This affects the function hanlp.load of the file plugins/hanlp_common/hanlp_common/reflection.py of the component Model Config Loading. This manipulation of the argument classpath causes deserialization. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
