A path traversal vulnerability has been identified in the R6410418 Jackrong-llm-finetuning-guide repository, specifically in the Qwen MTP GGUF pipeline. This issue affects the validate_indexed_tensors function within the qwen-mtp-gguf/scripts/qwen_mtp_gguf_pipeline.py
To address this vulnerability, the weight_map values should be validated before being processed. Absolute paths and segments that escape the directory should be rejected. After joining the paths, a verification step should ensure that the resolved path is within the allowed directory before opening the file.
