Machine-written summary

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

DotNetNuke.Core versions 9.0.0 through 9.13.9 and 10.0.0 before 10.02.0 are vulnerable to stored cross-site scripting in the Scheduler LogNotes. Extensions can write rich text into log notes that include scripts, which then run in the PersonaBar when displayed. Upgrade to DotNetNuke.Core 10.02.0 or later. The source gives few details about who can write the log notes.
