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
