ComfyUI before 0.30.0 fails to sanitize folder_name input in dataset save nodes, allowing attackers to write files to arbitrary paths outside the output directory. Attackers can load a crafted workflow that writes attacker-controlled content to arbitrary locations, enabling code execution through modified startup files or package initializers.
