CVE-2026-116545

All-in-One Video Gallery <= 5.0.0 - Authenticated (Subscriber+) Stored DOM-Based Cross-Site Scripting via 'track' Post Meta 'label' Field

Published Nov 6, 2026 CVSS 3.1 · 6.4 Medium EPSS < 1% KEV · Not listed
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.
