CVE-2025-62802: Dnnsoftware DotNetNuke

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to 10.1.1, the out-of-box experience for HTML editing allows unauthenticated users to upload files. This opens a potential vector to other security issues and is not needed on most implementations. This vulnerability is fixed in 10.1.1.
