Upstream source description

orval versions before 8.30.0 contain a code injection vulnerability in the @orval/core factory generator that fails to escape date default values in new Date() calls. Attackers can inject arbitrary expressions through apostrophes in OpenAPI schema defaults to execute code with the privileges of the consumer process when factoryMethods and useDates options are enabled.
