SCA: security update for @fastify/csrf-protection (GHSA-qrgf-9gpc-vrxw)

medium Tenable Cloud Security Plugin ID 418298

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - @fastify/csrf-protection is a plugin which helps protect Fastify servers against CSRF attacks. The CSRF
 protection enforced by the @fastify/csrf-protection library in combination with @fastify/cookie can be
 bypassed from network and same-site attackers under certain conditions. @fastify/csrf-protection supports
 an optional userInfo parameter that binds the CSRF token to the user. This parameter has been introduced
 to prevent cookie-tossing attacks as a fix for CVE-2021-29624. Whenever userInfo parameter is missing, or
 its value can be predicted for the target user account, network and same-site attackers can 1. fixate a
 _csrf cookie in the victim's browser, and 2. forge CSRF tokens that are valid for the victim's session.
 This allows attackers to bypass the CSRF protection mechanism. As a fix, @fastify/csrf-protection starting
 from version 6.3.0 (and v4.1.0) includes a server-defined secret hmacKey that cryptographically binds the
 CSRF token to the value of the _csrf cookie and the userInfo parameter, making tokens non-spoofable by
 attackers. This protection is effective as long as the userInfo parameter is unique for each user. This is
 patched in versions 6.3.0 and v4.1.0. Users are advised to upgrade. Users unable to upgrade may use a
 random, non-predictable userInfo parameter for each user as a mitigation. (CVE-2023-27495)
