Keymaker is a Mastodon Community Finder based Matrix Community serverlist page Server. In Keymaker before version 0.2.0, the assets endpoint did not check for the extension. The rust `join` method without checking user input might have made it abe to do a Path Traversal attack causing to read more files than allowed. This is fixed in version 0.2.0.
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.
