Problem Description

The backend module does not check whether a backend user has access to the requested site. Users with access to the module can therefore open the analytics dashboard of any site. (CVE-2026-112068)

The AJAX routes of the extension do not check whether a backend user has access to the related module or dashboard widget. Any backend user can therefore retrieve analytics data of the sites they have page access to. (CVE-2026-112070)
