WS-2023-0273
Date: August 19, 2025
In umami before 2.3.1 it is possible to reset the website data with a share link. When a user navigates to a /share/ URL, he receives a share token which is used for authentication. This token is later verified by useAuth. After the token is verified, the user can call most of the GET APIs that allow fetching stats about a website. The POST /reset endpoint is secured using canViewWebsite which is the incorrect verification for such destructive action. This makes it possible to completly reset all website data ONLY with view permissions.
