CVE-2022-41919 affects the Fastify web framework, allowing attackers to bypass CORS protection through incorrect Content-Type headers. Specifically, requests with "application/x-www-form-urlencoded", "multipart/form-data", or "text/plain" Content-Types can invoke routes expecting "application/json", leading to Cross-Site Request Forgery (CSRF) attacks. This vulnerability carries a high CVSS score of 8.8, indicating a network-based attack with low complexity and high impact on confidentiality, integrity, and availability, requiring user interaction. While patches are available in Fastify versions 4.10.2 and 3.29.4, there is currently no evidence of active exploitation, public exploit code, or significant community discussion.
