Mitigation checklist

Recommended fix / mitigation

To mitigate this vulnerability, ensure that any input strings processed by the `Joi.string().isoDate()` validation rule are capped in length before being passed to the 'joi' package. This can prevent the regular expression engine from consuming excessive resources and causing a denial of service.
