However, deserialized data or code can often be modified without using the provided accessor functions if it does not use cryptography to protect itself. Furthermore, any cryptography would still be client-side security -- which is a dangerous security assumption.\nData that is untrusted can not be trusted to be well-formed.\nWhen developers place no restrictions on \"gadget chains,\" or series of instances and method invocations that can self-execute during the deserialization process (i.e., before the object is returned to the caller), it is sometimes possible for attackers to leverage them to perform unauthorized actions, like generating a shell.","Draft","Base","Simple",1,false,[],{"title":96,"metaDescription":97,"keywords":98,"canonicalUrl":99,"structuredData":100},"What is CVE-2020-4305?
