The `validate` function exposed by the csaf-validator-lib executes arbitrary functions that a caller passes via arguments. These functions are not restricted to a trusted and predefined set of functions to validate CSAF documents, but can run arbitrary code.

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.
