Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Eclipse Ditto (org.eclipse.ditto:ditto) versions 3.0.0 up to 3.4.5 and 3.5.0 up to 3.5.6 are affected by cross-site scripting in the Ditto Explorer user interface. An attacker can exploit reflected XSS through input fields that are stored only in browser storage, and stored XSS by persisting Things that run scripts when other authorized users view them, which requires an authenticated and authorized account. Upgrade to version 3.4.5 or 3.5.6.
