Advisory
Source description from Wordfence Intelligence, credited to KoreaInfoSec.
The All-in-One Video Gallery plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.8.5 via the 'vdl' parameter. This makes it possible for authenticated attackers, with subscriber-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. A Subscriber-level attacker can plant an internal or loopback URL in the `mp4` post meta of a newly created `aiovg_videos` post via XML-RPC `wp.newPost`, then trigger the unauthenticated `?vdl=<post_id>` endpoint to force the server to fetch that URL and stream the full response body back to the requester.
