CVE-2025-59821

DNN vulnerable to Reflected Cross-Site Scripting (XSS) using url to profile

Published: Sep 23, 2025Updated: Sep 29, 2025 Sources: CVE List NVD GHSA BDUCWE-79

Description

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.1.0, DNN’s URL/path handling and template rendering can allow specially crafted input to be reflected into a user profile that is returned to the browser. In these cases, the application does not sufficiently neutralize or encode characters that are meaningful in HTML, so an attacker can cause a victim’s browser to interpret attacker-controlled content as part of the page’s HTML. This issue has been patched in version 10.1.0.
