Arbitrary File Overwrite (AFO) in superagi.controllers.resources.upload in TransformerOptimus SuperAGI 0.0.14 allows remote attackers to overwrite arbitrary files via unsanitised filenames submitted to the file upload endpoint, due to improper handling of directory traversal in os.path.join() and lack of path validation in get_root_input_dir().
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.
