CWE ID 352

Summary

CVE-2023-31999 is a vulnerability that affects all versions of @fastify/oauth2. The vulnerability is related to the usage of a statically generated state parameter that is used across all requests for all users. This parameter is meant to prevent Cross-Site Request Forgery (CSRF) attacks and should be unique per user. However, in this case, it is not properly connected to the user's session. The default behavior change in version 7.2.0 addresses this issue by storing the state in a cookie with the http-only and same-site=lax attributes set, and generating a unique state for every user. The vulnerability has a high base severity score of 8.8 and poses a potential danger to organizations as it can lead to unauthorized access, data breaches, and compromise of user sessions. Organizations should upgrade to version 7.2.0 or later to remediate this vulnerability and enhance their system's security against CSRF attacks.
