# Joomla jDownloads: authenticated path traversal lets files be moved or read

Link for people: https://infrastack.ai/live/CVE-2026-117542 (this .md is for agents)

jDownloads, a Joomla extension for file downloads, is affected by a path traversal flaw in the update_file parameter. A logged-in user can read file contents outside the permitted directory and move source files from their original locations.

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

## How to check

- Check the installed jDownloads version in the Joomla extensions manager or the extension's manifest file.
- Confirm whether the site uses the jDownloads extension at all.

## Fix

- jDownloads versions before `4.1.8` are affected; move to `4.1.8` or later.

## Timeline

- 2026-11-12T19:40:13+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-117542

## From the sources

Joomla Extension - jdownloads.com - Authenticated path traversal in jDownloads < 4.1.8 - A manipulated `update_file` form parameter could bypass the intended server-file selection restrictions and move files from outside the permitted selection directory or assign them to a download. This could expose file contents and remove source files from their original locations.
