Kohya_ss is a GUI for Kohya's Stable Diffusion trainers. Kohya_ss is vulnerable to a path injection in the `common_gui.py` `add_pre_postfix` function. This vulnerability is fixed in 23.1.5.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
