Description
Winter CMS is a content management system built on the Laravel PHP framework. From 1.1.0 until 1.2.14, Backend\Widgets\Lists::evalImageTypeValue() interpolates the result of ImageResizer::filterGetUrl() into a single-quoted image source attribute without escaping it. In a third-party plugin that renders an attacker-influenced value through an image list column, an unsupported image value is returned verbatim, can break out of the attribute, and can inject event handlers that execute when a backend user views the list. Winter core ships no image list column, so a default installation is unaffected. This issue is fixed in version 1.2.14.
