Details
As written in the advisory (Markdown source, shown as plain text).
### 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
