# Nging: authenticated users can list server directories via autocomplete endpoint

Nging through 5.3.5 has an endpoint, /user/autocomplete_path, that lists directories for any path a user supplies. A logged-in backend user without file-manager permission can enumerate directories the Nging process can read and confirm that specific files exist.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Nging version against `5.3.5` and below.
- Look for the `/user/autocomplete_path` route in the deployed Nging backend.

## From the sources

Nging through 5.3.5 contains an information disclosure vulnerability that allows any authenticated backend user to list host directories by abusing the public-tagged /user/autocomplete_path endpoint. Low-privileged users without file-manager permission can supply arbitrary paths in the query parameter to enumerate directories readable by the Nging process and confirm specific files exist.
