WP Import Export Lite <= 3.9.30 — Authenticated (Administrator+) Server-Side Request Forgery via 'file_url' Parameter

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under WP Import Export Lite.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 3.9.31, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch WP Import Export Lite to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to 밥김국.

The WP Import Export Lite plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to and including 3.9.30 via the wpie_import_upload_file_from_url AJAX action. The plugin's URL downloader first calls wp_safe_remote_get() (which correctly blocks private/reserved IP ranges), but when that call returns a WP_Error — the exact outcome for any blocked internal host — the Download::download_file() method falls back to GuzzleHttp\Client::request() with the original attacker-supplied URL and no SSRF protection (and with TLS verification disabled). This makes it possible for authenticated attackers, with administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services such as the cloud metadata endpoint at 169.
