CVE-2022-41919 Information

Description

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 pplication/x-www-form-urlencoded\ \multipart/form-data\ or ext/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'.
