## Technical details

A server-side request forgery (SSRF) vulnerability exists in the DistributionController.isValidHttpEndpoint function within app/Services/GeoFlow/GenericHttpEndpointResolver.php. The vulnerability arises from insufficient validation of the endpoint_url parameter, allowing an attacker to supply a malicious URL that causes the server to make requests to unintended destinations. The attack is network-accessible and requires no authentication. An attacker can exploit this to probe internal network resources, access internal services, or facilitate data exfiltration. A patch is available in version 2.1.1 (commit 67abfd864a15d169a78429f3290c91cb3b93e849); upgrading is recommended.
