Machine-written summary

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

DotNetNuke.Core versions before 9.13.10 and from 10.0.0 before 10.2.0 are affected by a stored cross-site scripting flaw in the module title, which accepts rich text that can include scripts. The source gives few details about who can enter these titles or exactly when the scripts run. Upgrade to DotNetNuke.Core 9.13.10 or 10.2.0, or later in the respective branch.
