All-in-One Video Gallery vulnerabilities

The WordPress plugin 'All-in-One Video Gallery' (versions up to 4.9.7) is vulnerable to Stored XSS due to improper neutralization of input during web page generation. A malicious script stored in the database executes for users visiting the site.

The All-in-One Video Gallery registers a public, unauthenticated file-download handler triggered by `?vdl=<post_id>` on any `aiovg_videos` post. It reads the post's `mp4` meta value and streams that URL's response back to the requester.

The All-in-One Video Gallery plugin for WordPress up to version 4.8.5 is vulnerable to Server-Side Request Forgery (SSRF) via the 'vdl' parameter. An authenticated attacker with subscriber-level access can make arbitrary web requests from the server, including to internal services, and read their responses.
