Uptodown APK Download Widget < 0.1.11 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The Uptodown APK Download Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'utd-widget' shortcode in all versions up to, and including, 0.1.10 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
