Vulnerability in All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos — CVE-2026-116545

What to do now

Update All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos to 5.1.0 or later.

Affected versions

• Everything up to and including 5.0.0

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.
