SCA: security update for @fastify/passport (GHSA-2ccf-ffrj-m4qw)

medium Tenable Cloud Security Plugin ID 408854

Description

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

 - @fastify/passport is a port of passport authentication library for the Fastify ecosystem. The CSRF (Cross-
 Site Request Forger) protection enforced by the `@fastify/csrf-protection` library, when combined with
 `@fastify/passport` in affected versions, can be bypassed by network and same-site attackers.
 `fastify/csrf-protection` implements the synchronizer token pattern (using plugins `@fastify/session` and
 `@fastify/secure-session`) by storing a random value used for CSRF token generation in the `_csrf`
 attribute of a user's session. The `@fastify/passport` library does not clear the session object upon
 authentication, preserving the `_csrf` attribute between pre-login and authenticated sessions.
 Consequently, CSRF tokens generated before authentication are still valid. Network and same-site attackers
 can thus obtain a CSRF token for their pre-session, fixate that pre-session in the victim's browser via
 cookie tossing, and then perform a CSRF attack after the victim authenticates. As a solution, newer
 versions of `@fastify/passport` include the configuration options: `clearSessionOnLogin (default: true)`
 and `clearSessionIgnoreFields (default: ['passport', 'session'])` to clear all the session attributes by
 default, preserving those explicitly defined in `clearSessionIgnoreFields`. (CVE-2023-29020)
