A vulnerability has been found in R6410418 Jackrong-llm-finetuning-guide up to ef2b17f2798cd18cd85375080c35a58397ad0d09. This vulnerability affects the function extract_mtp_heads of the file qwen-mtp-gguf/scripts/qwen_mtp_gguf_pipeline.py of the component MTP weight_map Handler. The manipulation of the argument shard_name leads to path traversal. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.
