NocoDB through 0.106.0 (or 0.109.1) has a path traversal vulnerability that allows an unauthenticated attacker to access arbitrary files on the server by manipulating the path parameter of the /download route. This vulnerability could allow an attacker to access sensitive files and data on the server, including configuration files, source code, and other sensitive information.
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.
