## Summary

The All-in-One Video Gallery WordPress plugin has a stored DOM-based cross-site scripting flaw. A remote attacker with a low-privilege, subscriber-level account can inject scripts into pages that run in the browser of any user who opens the affected page. The flaw only applies when the plugin's Player Library is set to Plyr/Vidstack instead of the default Video.js.

## Affected

- plugins360 All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos: through 5.0.0

## Description

The All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'custom_fields[].value.label (for key='track')' parameter in all versions up to, and including, 5.0.0 due to insufficient input sanitization and output escaping. 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. Exploitation requires the site's Player Library option to be configured as Plyr/Vidstack (aiovg_player_settings[player]='vidstack') rather than the Video.js default, as the DOM innerHTML sink exists only in the Plyr/Vidstack template path.
