## Overview

The All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'more_link' parameter in all versions up to, and including, 4.9.7 due to insufficient input sanitization and output escaping. 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.

## Affected

- `all-in-one_video_gallery_video_player_galleries_for_youtube_vimeo_self-hosted_videos <= 4.9.7`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
