Server-Side Request Forgery in All-in-One Video Gallery WordPress Plugin

Publication date: 2026-07-10

Last updated on: 2026-07-10

Assigner: Wordfence

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.

Executive Summary

The All-in-One Video Gallery plugin for WordPress has a Server-Side Request Forgery (SSRF) vulnerability in all versions up to and including 4.8.5. This vulnerability exists in the 'vdl' parameter, allowing authenticated users with subscriber-level access or higher to make the web application send requests to arbitrary locations.

An attacker can plant an internal or loopback URL in the 'mp4' post meta of a newly created 'aiovg_videos' post using the XML-RPC 'wp.newPost' method. Then, by triggering the unauthenticated '?vdl=<post_id>' endpoint, the server fetches the specified URL and streams the full response back to the attacker.

Impact Analysis

This vulnerability allows an attacker with subscriber-level access to make the server perform requests to arbitrary internal or external locations. This can be used to query and modify information from internal services that are normally inaccessible.

Because the attacker can retrieve the full response body from these requests, sensitive internal data could be exposed. This could lead to information disclosure and potentially unauthorized modification of internal resources.
