GHSA-5gmf-3c43-q73v

ZendFramework vulnerable to Cross-site Scripting

6.1 MediumFix available

Zend\Debug, Zend\Feed\PubSubHubbub, Zend\Log\Formatter\Xml, Zend\Tag\Cloud\Decorator, Zend\Uri, Zend\View\Helper\HeadStyle, Zend\View\Helper\Navigation\Sitemap, and Zend\View\Helper\Placeholder\Container\AbstractStandalone were not using Zend\Escaper when escaping HTML, HTML attributes, and/or URLs. While most were performing some escaping, because they were not using context-appropriate escaping mechanisms, they could potentially be exploited to perform Cross Site Scripting (XSS) attacks.
