Cross-Site Scripting (XSS) in WWBN/AVideo (CVE-2026-47694)
Summary
Cross-site scripting in WWBN/AVideo (CVE-2026-47694). Risk of unauthorized operations or information disclosure. Exploitable via category_description.
Original description
The description as published by the source.
Summary
AVideo stores category descriptions from user input and later renders category_description as raw HTML in the Gallery view. A user who can create or edit
categories can store JavaScript in a category description, which executes when another user views the affected Gallery/category page.
This is a stored XSS in the category description field, separate from previously fixed XSS issues in video titles or comments.

}
Sink:
plugin/Gallery/view/mainAreaCategory.php
" style="display: none;"><?php echo $videos[0]['category_description']; ?>
The value is rendered without htmlspecialchars(), htmlentities(), HTMLPurifier, or equivalent output encoding.
