Machine-written summary

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

DotNetNuke.Core versions before 9.13.9 are vulnerable to stored cross-site scripting through uploaded SVG files. Uploaded SVG files can contain scripts that run when the file is rendered inline, so an attacker who can upload files can run script in other users' browsers. Upgrade to DotNetNuke.Core 9.13.9 or later.
