Machine-written summary

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

DNN.PLATFORM versions from 6.0.0 before 10.0.1 are vulnerable to stored cross-site scripting in the Activity Feed Attachments endpoint. An attacker who can send a specially crafted request can inject scripts that then render in the feed, which can run in other users' browsers. The fix is to upgrade to version 10.0.1. The source gives few details about the required privileges.
