A security flaw has been discovered in Shaarli up to 0.16.3. The affected element is the function MetadataController of the file application/front/controller/admin/MetadataController.php of the component Admin Metadata Endpoint. Performing a manipulation of the argument url results in server-side request forgery. The attack may be initiated remotely. Upgrading to version 0.16.4 is sufficient to fix this issue. The patch is named 8ca4de8e7c932a684481f5fbb1229fe16de1f4d2. It is advisable to upgrade the affected component.
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.
