Summary: Uncaught Exception in fastify-multipart

Details: ### Impact This is a bypass of CVE-2020-8136 (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-8136). By providing a `name=constructor` property it is still possible to crash the application. The original fix only checks for the key `__proto__` (https://github.com/fastify/fastify-multipart/pull/116). All users are recommended to upgrade ### Patches v5.3.1 includes a patch ### Workarounds No workarounds are possible. ### References Read up https://www.fastify.io/docs/latest/Guides/Prototype-Poisoning/ ### For more information If you have any questions or comments about this advisory: * Open an issue in [https://github.com/fastify/fastify-multipart](https://github.com/fastify/fastify-multipart) * Email us at [[email protected]](mailto:[email protected])
