FoodCoopShop is open source software for food coops and local shops. Versions starting with 3.2.0 prior to 3.6.1 are vulnerable to server-side request forgery. In the Network module, a manufacturer account can use the `/api/updateProducts.json` endpoint to make the server send a request to an arbitrary host. This means that the server can be used as a proxy into the internal network where the server is. Furthermore, the checks on a valid image are not adequate, leading to a time of check time of use issue. For example, by using a custom server that returns 200 on HEAD requests, then return a valid image on first GET request and then a 302 redirect to final target on second GET request, the server will copy whatever file is at the redirect destination, making this a full SSRF. Version 3.6.1 fixes this vulnerability.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
