Winter CMS is vulnerable to Stored Cross Site Scripting (XSS). The vulnerability is due to improper sanitization within the rename functionality of files after uploads to the Media Manager. This issue can be exploited by an attacker with the media.manage_media permission to upload a file and later rename them to malicious payload to inject JavaScript into the application.
