Summary

The All-in-One Video Gallery WordPress plugin before 5.0.0 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embedded, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.
