The validate JSON endpoint of the Secvisogram csaf-validator-service in versions < 0.1.0 processes tests with unexpected names. This insufficient input validation of requests by an unauthenticated remote user might lead to a partial DoS of the service. Only the request of the attacker is affected by this vulnerability.
