Description

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.

• CWE-918Server-Side Request Forgery (SSRF)The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
