What is CVE-2026-12123?

The All-in-One Video Gallery plugin for WordPress contains a vulnerability that allows authenticated attackers with subscriber-level access and higher to perform Server-Side Request Forgery (SSRF). By exploiting the 'vdl' parameter, these attackers can make unauthorized web requests from the web application, potentially exposing sensitive internal services. This occurs when a user creates a new video post via XML-RPC and sets an internal or loopback URL in the 'mp4' metadata, triggering the plugin's endpoint to retrieve and return the content of that URL to the requestor.

Affected Version(s)

All-in-One Video Gallery 0 <= 4.8.5
