parisneo/lollms-webui versions v9.9 to the latest are vulnerable to a directory listing vulnerability. An attacker can list arbitrary directories on a Windows system by sending a specially crafted HTTP request to the /open_file endpoint.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as “/abs/path” that can resolve to a location that is outside of that directory.
