Machine-written summary

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

DotNetNuke.Core versions before 10.1.1 are affected by stored cross-site scripting through uploaded SVG files, because the sanitization of SVG content does not cover all XSS cases. An attacker who can upload an SVG file can get script to run in the browser of users who view it, which could allow session hijacking or data theft. Upgrade to DotNetNuke.Core 10.1.1 or later, which contains the fix.
