Description
The All-in-One Video Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode attributes such as 'more_link' in all versions up to, and including, 4.9.7 due to insufficient output escaping: URLs were placed into inline onclick JavaScript strings using only esc_url(), allowing HTML-encoded quotes to break out, and video tag attributes were combined into HTML without escaping keys or values. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
