Affected packages

• npm fastify: >= 4.0.0, < 4.10.2 → fixed in 4.10.2 • npm fastify: >= 3.0.0, < 3.29.4 → fixed in 3.29.4

Description

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`.
