Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

DotNetNuke.Core versions before 10.1.0 are vulnerable to reflected cross-site scripting through a specially crafted URL used to view a user profile. An attacker could get a victim to open such a link, causing attacker-controlled content to run as HTML in the victim's browser. Upgrade to DotNetNuke.Core 10.1.0 or later.
