From 1.2.10 through 1.2.12, authenticated backend users with the backend.manage_editor permission can store custom Markup Styles that are compiled by the LESS parser and rendered without sanitization on every backend page, allowing stored cross-site scripting. This issue is fixed in version 1.2.13.
