BlueprintUE Self-Hosted Edition 1.0.0 before 4.3.5 contains a resource exhaustion vulnerability that allows unauthenticated attackers to fill server storage by repeatedly creating anonymous blueprints. Attackers can send large requests to HomeController::doProcessCreateBlueprint() with a 'never' expiration, bypassing purges to fill the disk and deny service.
