Machine-written summary

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

DotNetNuke.Core versions before 10.1.0 are affected. A user who can edit modules, such as an administrator or content editor, can set a module title containing scripts, which enables stored cross-site scripting attacks. Upgrade to DotNetNuke.Core 10.1.0 or later. The source describes a new setting in the Security module of the Persona Bar that controls whether HTML is allowed in module titles.
