What is CVE-2024-47819?
CVE-2024-47819 is a medium-severity cross-site scripting vulnerability in Umbraco Umbraco Cms, published on 22 Oct 2024. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
Umbraco, a free and open source .NET content management system, has a cross-site scripting vulnerability starting in version 14.0.0 and prior to versions 14.3.1 and 15.0.0. This can be leveraged to gain access to higher-privilege endpoints, e.g. if you get a user with admin privileges to run the code, you can potentially elevate all users and grant them admin privileges or access protected content. Versions 14.3.1 and 15.0.0 contain a patch. As a workaround, ensure that access to the Dictionary section is only granted to trusted users.
