Summary
Fastify: Incorrect Content-Type parsing can lead to CSRF attack
Details

Impact

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.

Patches

For 4.x users, please update to at least 4.10.2 For 3.x users, please update to at least 3.29.4

Workarounds

Implement Cross-Site Request Forgery protection using @fastify/csrf.
