Fastify vulnerable to Cross-Site Request Forgery (CSRF) attack via incorrect content type

Fastify is a web framework with minimal overhead and plugin architecture. The attacker can use the incorrect `Content-Type` to bypass the `Pre-Flight` checking of `fetch`. `fetch()` requests with Content-Type’s essence as "application/x-www-form-urlencoded", "multipart/form-data", or "text/plain", could potentially be used to invoke routes that only accepts `application/json` content type, thus bypassing any CORS protection, and therefore they could lead to a Cross-Site Request Forgery attack. This issue has been patched in version 4.10.2 and 3.29.4. As a workaround, implement Cross-Site Request Forgery protection using `@fastify/csrf'.

跨站请求伪造(CSRF)

Fastify 跨站请求伪造漏洞

Fastify是OpenJS基金会的一款用于Node.js的开源Web框架。 Fastify 存在跨站请求伪造漏洞，该漏洞源于攻击者可以使用不正确的Content-Type来绕过检查，从而绕过任何CORS保护，可能导致跨站请求伪造攻击。
