A flaw was found in React Router. Insufficient Cross-Site Request Forgery (CSRF) checks in the framework mode allow a remote attacker to bypass these protections on PUT, PATCH, and DELETE requests. This could lead to a low integrity impact, where an attacker might be able to perform unintended actions on behalf of a user. Modern browser security features, such as Cross-Origin Resource Sharing (CORS) preflight and SameSite cookies, significantly limit the practical exploitability of this vulnerability.
