CVE-2026-124589: Path Traversal (CVSS 6.3)

Description

A weakness has been identified in lxtGH OMG-Seg up to f3b26b609bae919760cd3ccf09c36179bb8624a0. This affects the function load_state_dict_into_model of the file omg_llava/xtuner/utils/handle_moe_load_and_save.py of the component MoE Shard Checkpoint Loader. Executing a manipulation of the argument weight_map can lead to path traversal. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.
