What is CVE-2023-51701?

The Fastify plugin 'fastify-reply-from' is designed for HTTP request forwarding to other servers. However, a flaw exists wherein the plugin misinterprets the incoming request body due to improper handling of the 'ContentType: application/json; charset=utf-8' header. This exploitation can result in security checks being bypassed, raising significant concerns regarding the integrity of the requesting process. Users are urged to upgrade to version 9.6.0 or later to mitigate this issue.
