📄 Description (English)

The Auto Thumbnail plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'thumbnails' shortcode in all versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on the shortcode's 'width' and 'height' attributes in the athn_thumbnails() function, which are concatenated directly into an HTML <img> tag. 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.

🤖 AI Executive Summary

The Auto Thumbnail WordPress plugin versions up to 1.0 contains a Stored XSS vulnerability in the thumbnails shortcode due to insufficient sanitization of width and height attributes. Authenticated contributors can inject malicious scripts that execute for all users viewing affected pages.
