Name of the Vulnerable Software and Affected Versions Smart App Banners plugin for WordPress versions prior to 1.3

Description The Smart App Banners plugin for WordPress is susceptible to Stored Cross-Site Scripting. This is due to insufficient input sanitization and output escaping on user-supplied attributes within the 'size' and 'verticalalign' parameters of the 'app-store-download' shortcode. Authenticated attackers with Contributor-level access or higher can inject arbitrary web scripts into pages. These scripts will execute when a user accesses the affected page.

Recommendations Update the Smart App Banners plugin to version 1.3 or later.
