## Description

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to 10.1.1, sanitization of the content of uploaded SVG files was not covering all possible XSS scenarios. This vulnerability exists because of an incomplete fix for CVE-2025-48378. This vulnerability is fixed in 10.1.1.

## What to do

- Check your stack: if you ship or depend on dnnsoftware Dnn.Platform, DotNetNuke.Core, upgrade to a fixed version (10.1.1) per the references below.
