Impact

This is a bypass of CVE-2020-8136 (https://vulners.com/cve/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.
