CVE-2026-9856 is a path traversal vulnerability in huggingface/transformers versions up to 5.8.0.dev0. It allows an attacker to write arbitrary files by exploiting improper validation of filenames derived from the chat_template dictionary keys in the save_pretrained() methods of PreTrainedTokenizerBase and ProcessorMixin. This can be triggered when a victim downloads and saves a maliciously crafted tokenizer or processor from a Hugging Face Hub repository. Multiple processors inheriting from ProcessorMixin are affected, including Idefics, Florence, Gemma, Phi, and Qwen-VL.
