Summary

The rolling release of R6410418 Jackrong-llm-finetuning-guide up to ef2b17f2798cd18cd85375080c35a58397ad0d09 is affected, and no version information is disclosed. The validate_indexed_tensors function in qwen-mtp-gguf/scripts/qwen_mtp_gguf_pipeline.py does not restrict paths taken from the weight_map argument (CWE-22). A remote attacker with low privileges can manipulate weight_map to reach paths outside the intended directory, and user interaction is required. A public exploit is linked in the references.
