## Description

The All-in-One Video Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'image' video post meta in all versions up to, and including, 5.0.0 due to insufficient input sanitization of the meta value when it is written (for example through XML-RPC custom fields) and missing output escaping when it is printed in the admin video list. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that execute whenever a user, such as an administrator, accesses an affected page.
