Description

The All-in-One Video Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the YouTube video URL in all versions up to, and including, 4.9.7 due to the YouTube video ID being extracted from a URL-decoded value and concatenated into embed and thumbnail URLs without validation or sufficient output escaping. Since subscribers are granted the capability to create videos, this makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
