# WordPress Photo Engine plugin lets unauthenticated users delete media attachments

The Photo Engine (Media Organizer & Lightroom) WordPress plugin up to and including 6.5.6 fails to check authorization on its sync API. An unauthenticated attacker can permanently delete media attachments and upload new ones, and a Subscriber-level user can take a token from the admin page source to reach the same destructive actions.

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

## How to check

- Check the installed version of the Photo Engine (Media Organizer & Lightroom) plugin in WordPress admin under Plugins, or with `wp plugin get <plugin-slug> --field=version`
- Look for the `/?wplr-sync-api` endpoint responding on the site
- Check whether the Meow_WPLR_Sync_Admin admin guard is commented out in the plugin source

## Fix

- Update the Photo Engine (Media Organizer & Lightroom) plugin to a version later than `6.5.6`; the sources do not name the fixed version
- Until updated, deactivate the plugin or block the `/?wplr-sync-api` endpoint at the web server
- Restore deleted media from backups if the endpoint was reachable

## From the sources

The Photo Engine (Media Organizer & Lightroom) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.5.6 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to permanently delete arbitrary media attachments via wp_delete_attachment and upload new attachments to the site, actions that require the upload_files or edit_others_posts capabilities. A Subscriber-level user can obtain their own wplr_auth_token directly from the profile.php page source, because the admin screen guard in Meow_WPLR_Sync_Admin::__construct() is commented out, causing wp_localize_script to leak the token into every admin page view; this token can then be used from a cookie-less HTTP session to invoke destructive actions on the /?wplr-sync-api endpoint.
