Name of the Vulnerable Software and Affected Versions: DNN (formerly DotNetNuke) versions 6.0.0 through 10.0.0

Description: The issue allows a specially crafted request to inject scripts in the "Activity Feed Attachments" endpoint, which will then render in the feed, resulting in a cross-site scripting attack.

Recommendations: For versions 6.0.0 through 10.0.0, update to version 10.0.1 to resolve the issue. As a temporary workaround, consider restricting access to the "Activity Feed Attachments" endpoint until the update is applied.
