Two DotNetNuke packages are affected: DotNetNuke.Web and DotNetNuke.Core, both before 9.13.9. A specially crafted URL can inject a cross-site scripting payload that runs when a user triggers certain module actions. Upgrade DotNetNuke.Web and DotNetNuke.Core to 9.13.9 or later. The source gives few details about which module actions are involved.
