Ubuntu Security Notice 6264-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

### 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-co...
