An authorization bypass vulnerability has been identified in LinkStack, a self-hosted link management platform, in versions through 4.8.6. The issue arises in the Management Endpoint, specifically within the 'saveLink' function of 'UserController.php'. This vulnerability allows authenticated users to modify, reorder, or delete links that they do not own, by exploiting endpoints that fail to properly verify link ownership. The affected endpoints are 'POST /studio/edit-link', 'POST /studio/sort-link', and 'GET /clearIcon/{id}'.
The vulnerability can be fixed by applying the 'link-id' middleware to the unprotected routes and updating the middleware to check for link ownership. This has been proposed in a pull request that is awaiting acceptance.
