A flaw has been found in go-sonic sonic up to 1.1.4. The affected element is the function FetchTheme of the file service/theme/git_fetcher.go of the component Theme Fetching API. Executing manipulation of the argument uri can lead to server-side request forgery. The attack may be launched remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Weakness
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.
