Buffercode » Random Banner : Security Vulnerabilities, CVEs,

The Random Banner WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient escaping via the category parameter found in the ~/include/models/model.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 4.1.4. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.

Cross-site scripting (XSS) vulnerability in the Random Banner plugin 1.1.2.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the buffercode_RBanner_url_banner1 parameter in an update action to wp-admin/options.php.
